Six Proven Facts About Cancer:

February 22nd, 2010


Presently, there is no known factor that can be said that is the basic cause or causes of cancer. There are some facts that have long been held about cancer that has been discovered to be false, but new facts about this deadly have equally emerged. The lists below are however, some of the facts that are widely believed to be the true facts about cancer.

1) Heredity is among the factors that influence the occurrences of cancer in human life. However, the hereditary lines in an individual cannot be used to diagnose a cancer victim. Rather, this makes it difficult if not impossible to actually say what will become of a cancer patient. There has been striking similarity in the development of breast cancers in the life of people of the same family, especially with identical twins.

2) Cancer is not contagious. There is no proven fact that shows that one can contact cancer by taking care of another cancer patient.

3) There is no scientifically proven influence that diet has on the development of any type of cancer. There are people that believe that some diets has some contributing factors towards the development of cancer, but since there is no scientifically proved evidence presently either in support of it or not, there is no basis also to say that such belief is wrong.

4) A repeated injury or a long term irritation has the potential to cause cancer.

5) Cancer sometimes behaves like infections, and certain animal experiments of malignant tumors seemed to stimulate cancer formation.

6) Certain hormones in the body, like the estrogenic hormones of the ovary stimulate the growth of cancer in the body. The implication of this is a suggestion that the existence of unbalanced hormone formation or growth in the body can lead to the development of cancer.

These are the basic facts one should know about cancer. However, we need to know that everyday, discoveries are coming out and new facts are equally coming out, so one should not take the above as the only things or the only facts that is worthy to note about cancer. There are other important things that we need to take note of about this deadly disease called cancer. Let’s discuss some of them as they will equally make some meanings in the topic of our discussion today.

A) One of the recognized causes of the cancer of the lower lip is smoking, especially pipe smoking. Also, it can be said authoritatively that one of the major causes of lung cancer is inhaled cigarette smoke. So if we can do away with this, we are doing a whole lot of good for our health.

B) Cancer of the tongue is mostly preceded by either jagged teeth, rough filling of the teeth or even syphilis of the tongue.

C) Cancer of the skin is not common except when this part of the body comes under undue or severe burns on the skin.

D) Cancer of the mouth is more common with those that chew often or hold objects long in their mouth thereby putting the mouth to undue pressure.

E) Excessive exposure to sunlight and wind can lead to skin cancer.

Cancer used to be classified as a disease that is more prevalent to the women folk, due largely the high incidence of breast cancer and other types of cancer that has to do with the sex organ, but there is a reversal of the trend today. More men suffer cancer these days than women. This is due largely to the increase of lung cancer among men. Avoiding all the causes mentioned above will guarantee 100% prevention of cancer, but will greatly reduce it. This is because there are other factors not mentioned here that can equally lead to cancer development in the body. So we should always be on the look out for any symptom that suggests that there is a development of cancer, then go me medical check and if it is discovered to be cancer and treated early, there will be better chance of success than when it has actually grown very large.

So if tobacco gives you cancer, and alcohol disorients you, then what is so bad about smoking pot?

February 22nd, 2010

How many counts of domestic abuse are caused by alcohol every year? As opposed to domestic abuse caused by marijuana? Or any violent confrontations while under the influence of pot? What’s the difference between a pot head and an alcoholic?

Crack and meth will destroy your body but is it fair to lump pot in that same category?

How To Cure Lung Cancer

February 22nd, 2010


Cancer is a class of diseases characterized by out of control cell growth. Lung cancer occurs when this uncontrolled cell growth begins in one or both lungs. The lungs are two large spongy organs located inside the chest cavity. Air is breathed into the trachea and moves down two tubes called bronchi, each going to a lung. Lung cancer occurs most often in adults between the ages of 40 and 70 who have smoked cigarettes for at least 20 years.

Over 1,400 victorians are diagnosed with lung cancer every year. Only about 2% of those diagnosed with lung cancer that has spread to other areas of the body are alive five years after the diagnosis, although the survival rates for lung cancers diagnosed at a very early stage are higher with approximately 49% surviving for five years or longer.

There are different types of lung cancer, depending on which cells are affected. The two main types are:

1. Small cell carcinom
Around 15 per cent of lung cancers are small cell carcinomas. This type of cancer spreads early and shows few early symptoms.

2. Non-small cell carcinoma
These cancers affect the cells that line the main bronchi.

Some lung tumors are metastatic from cancers elsewhere in the body. The lungs are a common site for metastasis. Since lung cancer tends to spread or metastasize very early in its course, it is a very life-threatening cancer and one of the most difficult cancers to treat. So, gain knowledge how to cure lung cancer.

Symptoms of lung cancer are varied depending upon where and how widespread the tumor is. Warning signs of lung cancer are not always present or easy to identify. Lung cancer symptoms may take years before appearing, usually after the disease is in an advanced stage.

Below is the following symptoms of lung cancer include :

1. Pain in the chest shoulder or back from coughing

2. A cough that does not go away or gets worse over time

3. Breathlessness and swallowing

4. Recurring pneumonia or chest infections

5. Wheezing or hoarseness may signal blockage

6. Unexplained weight loss

Lung cancer is categorized into stages according to its spread. This helps the doctors to decide on appropriate treatments. Lung cancer treatments also depend on the type of cancer, age, health status and additional personal characteristics. As there is usually no single treatment for cancer, patients often receive a combination of therapies and palliative care. More than one type of therapy may be prescribed to cure lung cancer.

Although the diagnostic techniques provided important information, extracting cancer cells and looking at them under a microscope is the only absolute way to diagnose lung cancer. This procedure is called a biopsy. If the biopsy confirms lung cancer, a pathologist will determine whether it is non-small cell lung cancer or small cell lung cancer.

Small cell lung cancer has two stages which is :

1. In the limited stage, the tumor exists in one lung and in nearby lymph nodes.

2. In the extensive stage, the tumor has infected the other lung as well as other organs in the body.

For non-small cell lung cancer, these stages are labeled from I to IV. The lower numbers indicate earlier stages where the cancer has spread less :

1. Stage I is when the tumor is found only in one lung and in no lymph nodes.

2. Stage II is when the cancer has spread to the lymph nodes surrounding the infected lung.

3. Stage III is when the cancer has spread to lymph nodes around the trachea, chest wall and diaphragm on the same side as the infected lung.

4. Stage IV is when the cancer has spread to lymph nodes on the other lung or in the neck.

5. Stage IV is when the cancer has spread throughout the rest of the body and other parts of the lungs.

As with most cancers, the results are best if the cancer is diagnosed in its earliest stages. However, some lung cancers aren’t diagnosed until they are quite advanced. Treatment may then be limited to easing the symptoms. To cure lung cancer depend on treatment option.

What are treatments for lung cancer :

1. Chemotherapy is an anti cancer drugs are given to stop cancer cells from multiplying. This treatment is most effective for small cell carcinoma.

2. Surgery to remove the affected part of the lung or an entire lung. This offers the best chance to cure lung cancer if the cancer has not spread beyond the lungs.

3. Radiotherapy use of x-rays to target and kill cancer cells. It may be used against some early stage lung cancers and to cure cancer in the lymph nodes from spreading further.

4. Targeted therapy is use of small molecules, often in tablet form that may be used after chemotherapy.

5. Clinical trialsis a participation in a clinical trial that investigates the safety and effectiveness of novel drugs may be offered.

Cancers that are closely linked to certain behaviors are the easiest to prevent. If you are a current tobacco user, quitting can still greatly reduce your chances of getting cancer. The most important preventive measure you can take to avoid lung cancer is to quit smoking. Many products such as nicotine gum, nicotine sprays, nicotine inhalers have been successfully used to help people trying to quit smoking.

What is the cause of lung cancer :

1. A person who smokes more than one pack of cigarettes per day has a risk of developing lung cancer 20-25 times greater than someone who has never smoked.

2. Cigar and pipe smoking increases the risk of lung cancer but not as much as smoking cigarettes.

3. Asbestos fibers are silicate fibers that can persist for a lifetime in lung tissue following exposure to asbestos. The workplace is a common source of exposure to asbestos fibers.

4. Radon gas is a natural chemically inert gas that is a natural decay product of uranium. With an estimated 12% of lung-cancer deaths attributable to radon gas.

5. Air pollution from vehicles, industry, and power plants can raise the likelihood of developing lung cancer in exposed individuals

Screening techniques are designed to find cancer at the earliest stage so that the most treatment options are available. Most lung cancers are detected in the late stages of the disease after they have spread and are harder to treat. Possible lung cancer screening tests include analysis of sputum cells, fiberoptic examination of bronchial passages and low-dose spiral CT scans.

Cancer and cancer treatments can make a person feel too tired to exercise. However, studies show that, physical activity can boost the energy levels of a person who has cancer.

Regular exercise improves functioning of the immune system and may increase survival rates in some cases. Aim for five to 20 minutes of moderate intensity exercise on most days of the week. See your doctor’s and get to know how to cure lung cancer.

What Is Lung Cancer And What Cause It

February 22nd, 2010

Lung cancer is the leading cause of cancer deaths in both women and men in the United States and throughout the world. Lung cancer has surpassed breast cancer as the leading cause of cancer deaths in women.


In the United States in 2007, 160,390 people were projected to die from lung cancer, which is more than the number of deaths from colorectal, breast, and prostate cancer combined.


Only about 2% of those diagnosed with lung cancer that has spread to other areas of the body are alive five years after the diagnosis, although the survival rates for lung cancers diagnosed at a very early stage are higher, with approximately 49% surviving for five years or longer.


Some lung tumors are metastatic from cancers elsewhere in the body. The lungs are a common site for metastasis. If this is the case, the cancer is not considered to be lung cancer. For example, if prostate cancer spreads via the bloodstream to the lungs, it is metastatic prostate cancer (a secondary cancer) in the lung and is not called lung cancer.


Cancer occurs when normal cells undergo a transformation that causes them to grow and multiply without the normal controls. The cells form a mass or tumor that differs from the surrounding tissues from which it arises. Tumors are dangerous because they take oxygen, nutrients, and space from healthy cells.


About 90% of lung cancers arise due to tobacco use. Cigarette smoking is the most important cause of lung cancer. Research as far back as the 1950s clearly established this relationship. Cigarette smoke contains more than 4,000 chemicals, many of which have been identified as causing cancer. A person who smokes more than one pack of cigarettes per day has a risk of developing lung cancer 20-25 times greater than someone who has never smoked.


However, Once a person quits smoking, his or her risk for lung cancer gradually decreases. About 15 years after quitting, the risk for lung cancer decreases to the level of someone who never smoked. Cigar and pipe smoking also increases the risk of lung cancer but not as much as smoking cigarettes.

Most lung tumors are malignant. This means that they invade and destroy the healthy tissues around them and can spread throughout the body.


The tumors can also spread to nearby lymph nodes or through the bloodstream to other organs. This process is called metastasis. When lung cancer metastasizes, the tumor in the lung is called the primary tumor, and the tumors in other parts of the body are called secondary tumors or metastatic tumors.


Adenocarcinoma (an NSCLC) is the most common type of lung cancer, making up 30%-40% of all cases. A subtype of adenocarcinoma is called bronchoalveolar cell carcinoma, which creates a pneumonia-like appearance on chest x-rays. Squamous cell carcinoma (an NSCLC) is the second most common type of lung cancer, making up about 30% of all lung cancers. Large cell cancer (another NSCLC) makes up 10% of all cases. SCLC makes up 20% of all cases. And finally, Carcinoid tumors account for only 1% of all cases.


Lung cancers are usually divided into two main groups that account for about 95% of all cases. These division into groups is based on the type of cells that make up the cancer. About 5% of lung cancers are of rare cell types, including carcinoid tumor, lymphoma, and others.


The two main types of lung cancer are characterized by the cell size of the tumor when viewed under the microscope. They are called small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC includes several subtypes of tumors. SCLCs are less common, but they grow more quickly and are more likely to metastasize than NSCLCs. Often, SCLCs have already spread to other parts of the body when the cancer is diagnosed.


Up to one-fourth of all people with lung cancer may have no symptoms when the cancer is diagnosed. These cancers usually are identified incidentally when a chest x-ray is performed for another reason. The majority of people, however, develop symptoms. The symptoms are due to direct effects of the primary tumor, to effects of metastatic tumors in other parts of the body, or to disturbances of hormones, blood, or other systems caused by the cancer.


Symptoms of primary lung cancers include cough, coughing up blood, chest pain, and shortness of breath. Symptoms of metastatic lung tumors depend on the location and size. About 30%-40% of people with lung cancer have some symptoms or signs of metastatic disease.


A cough that does not go away or gets worse over time should be evaluated by a health-care provider. Also, Coughing up blood (hemoptysis) occurs in a significant number of people who have lung cancer. Any amount of coughed-up blood is cause for concern. Chest pain is a symptom in about one-fourth of people with lung cancer. The pain is dull, aching, and persistent and may involve other structures surrounding the lung.


Additionally, shortness of breath usually results from a blockage to the flow of air in part of the lung, collection of fluid around the lung (pleural effusion), or the spread of tumor throughout the lungs. Wheezing or hoarseness may signal blockage or inflammation in the lungs that may go along with cancer. Finally, Repeated respiratory infections, such as bronchitis or pneumonia, can be a sign of lung cancer.

Oral Cancer – What is Oral Cancer

February 22nd, 2010

Cancer is defined as the uncontrollable growth of cells that invade and cause damage to surrounding tissue. Oral cancer appears as a growth or sore that does not go away. Oral cancer â?? which includes cancers of the lips, tongue, cheek, floor of the mouth, hard and soft palate, sinuses, and pharynx (throat) â?? can be life-threatening if not diagnosed and treated early.

The term oral cancer includes cancers of the mouth and the pharynx, part of the throat. About two-thirds of oral cancers occur in the mouth and about one-third are found in the pharynx. Oral cancer will be diagnosed in an estimated 28,000 Americans this year and will cause approximately 7,000 deaths. It is the 6th most common cancer in men and the 14th most common cancer in women.

Each year, more than 30,000 new cases of cancer of the oral cavity and pharynx are diagnosed and over 8,000 deaths due to oral cancer occur. The 5-year survival rate for these cancers is only about 50 percent. Mortality from oral cancer is nearly twice as high in some minorities (especially black males) as it is in whites. Methods used to treat oral cancers (surgery, radiation, and chemotherapy) are disfiguring and costly. Preventing high risk behaviors, that include cigarette, cigar or pipe smoking, use of smokeless tobacco, and excessive use of alcohol are critical in preventing oral cancers. Early detection is key to increasing the survival rate for these cancers.

Oral cancer can form in any part of the mouth or throat. Most oral cancers begin in the tongue and in the floor of the mouth. Anyone can get oral cancer, but the risk is higher if you are male, over age 40, use tobacco or alcohol or have a history of head or neck cancer. Frequent sun exposure is also a risk for lip cancer. Smoking and other tobacco use are associated with 70-80% of oral cancer cases. Smoke and heat from cigarettes, cigars, and pipes irritate the mucous membranes of the mouth. Use of chewing tobacco or snuff causes irritation from direct contact with the mucous membranes. Heavy alcohol use is another high-risk activity associated with oral cancer.

Oral cancer is as common as leukemia and kills more Americans each year than either skin or cervical cancer. Patients with oral cancer have a poor prognosis, and the 5-year survival rate of approximately 50% has remained unchanged for the past 50 years. Perhaps the single most important reason for this is the fact that oral cancers continue to be diagnosed in advanced stages. Research studies have repeatedly demonstrated that the survival rate for oral cancer patients increases dramatically when the diagnosis is established in early stages.

Oral cancer can spread quickly, early detection is important. An oral cancer exam can identify early signs of this disease. The exam is quick and painless, and can be done during your regular dental check-up. Be sure to tell your dentist if you notice persistent changes in your mouth or throat, such as sores, swelling, or numbness, or if you have difficulty eating or swallowing.

Approximately 35,000 new cases of oral cancer are diagnosed each year in the United States. Some 25 percent of those people will die of the disease. According to the American Cancer Society, oral cancer occurs almost as frequently as leukemia and claims more lives than melanoma or cervical cancer. Oral cancerâ??s incidence is rising among women, young people and non-smokers.

Low cost Mouth and Throat cancer surgery in India along with Medical Tourism and healthcare facilities

February 22nd, 2010

Mouth and Throat Cancer surgery in India is being provided to International as well as Indian patients at low, reasonable and affordable cost with best medical healthcare facilities for the patients to be treated. Hospitals providing the mouth and throat cancer surgery in India are all corporate and multispecialty. These hospitals are having fully equipped and research based staff available 24 hours for the patients on an emergency basis. The oral cavity (mouth) and the upper part of the throat (pharynx) have roles in many important functions, including breathing, talking, chewing, and swallowing. The mouth and upper throat are sometimes referred to as the oropharynx. The important structures of the mouth and upper throat include the following:

       Lips

       Inside lining of the cheeks (buccal mucosa)

       Teeth

       Gums

       Tongue

       Floor of the mouth

       Back of the throat, including the tonsils (oropharynx)

       Roof of the mouth (the bony front part [hard palate] and the softer rear part [soft palate])

       Area behind the wisdom teeth

       Salivary glands

Many different cell types make up these different structures. Cancer occurs when normal cells undergo a transformation whereby they grow and multiply without normal controls.

 

 

Mouth and Throat cancer Causes:

Tobacco use is by far the most common risk factor for cancers of the mouth and throat. Both smoking and “smokeless” tobacco (snuff and chewing tobacco) increase the risk of developing cancer in the mouth or throat.

       All forms of smoking are linked to these cancers, including cigarettes, cigars, and pipes. Tobacco smoke can cause cancer anywhere in the mouth and throat as well as in the lungs, the bladder, and many other organs in the body. Pipe smoking is particularly linked with lesions of the lips, where the pipe comes in contact with the tissue.

       Smokeless tobacco is linked with cancers of the cheeks, gums, and inner surface of the lips. Cancers caused by smokeless tobacco use often begin as leukoplakia or erythroplakia.

Other risk factors for mouth and throat cancer include the following:

       Alcohol use: At least three quarters of people who have a mouth and throat cancer consume alcohol frequently. People who drink alcohol frequently are 6 times more likely to develop one of these cancers. People who both drink alcohol and smoke often have a much higher risk than people who use only tobacco alone.

       Ultraviolet light exposure: People who spend a lot of time in sunlight, such as those who work outdoors, are more likely to have cancer of the lip.

       Chewing betel nut, a prevalent practice in India and other parts of South Asia, has been found to result in mucosa carcinoma of the cheeks. Mucosa carcinoma accounts for less than 10% of oral cavity cancers in the United States but is the most common oral cavity cancer in India.

       Human papillomavirus (HPV) infection: Several strains of HPV are associated with cancers of the cervix, vagina, vulva, and penis. The link between HPV and oral cancers is not known, but HPV infection is believed to increase the risk of oral cancers in some people.

These are risk factors that can be avoided in some cases. For example, you can choose to not smoke, thus lowering your risk of mouth and throat cancer. The following risk factors are outside of your control:

       Age: The incidence of mouth and throat cancers increases with advancing age.

       Sex: Mouth and throat cancer is twice as common in men as in women. This may be related to the fact that more men than women use tobacco and alcohol.

The relationship between these risk factors and an individual’s risk is not well understood. Many people who have no risk factors develop mouth and throat cancer. Conversely, many people with several risk factors do not. In large groups of people, these factors are linked with higher incidence of oropharyngeal cancers.

Mouth and Throat Cancer Treatment

After you have been evaluated by a surgical or radiation oncologist to treat your cancer, you will have ample opportunity to ask questions and discuss which treatments are available to you.

       Your doctor will present each type of treatment, give you the pros and cons, and make recommendations.

       Treatment for mouth and throat cancer depends on the type of cancer and whether it has affected other parts of the body. Factors such as your age, your overall health, and whether you have already been treated for the cancer before are included in the treatment decision-making process.

       The decision of which treatment to pursue is made with your doctor (with input from other members of your care team) and your family members, but ultimately, the decision is yours.

       Be certain you understand exactly what will be done and why, and what you can expect from your choices. With oral cancers, it is especially important to understand the side effects of treatment.

Like many cancers, mouth and throat cancer is treated on the basis of cancer stage. The most widely used therapies are surgery and radiation therapy. Chemotherapy is used in some advanced cases. Your treatment plan will be individualized for your specific situation.

Why India:

Causes of Lung Cancer – Information You Need to Know

February 22nd, 2010

More men and women die from lung cancer than any other cancers. Who is most susceptible to this disease? Nearly 70 percent of the elderly 65 and older will be diagnosed with this disease. Three percent of lung cancer cases have appeared in people younger than 45 years old.

Until the 1930s, cancer of the lungs was not as prevalent but still quite common. However, once there was an increase of tobacco smoking use, lung cancer cases rose drastically. As information and education circulates about the hidden dangers of smoking, lung cancer related deaths are beginning to see a decline. Despite all the education and the public awareness, it’s still a common human cancer. For women, breast cancer is no longer the number one killer. Lung cancer has exceeded breast cancer related deaths.

Lung Cancer Causes

Smoking – Most lung cancer related deaths (about 90 percent) have been associated with smoking. Each time a person smokes a cigarette, they increase their chances of getting lung cancer. Based upon doctors’ formula regarding the quantity of packs to the amount of years smoked, someone who has a 30 pack to year history has a greater chance to develop lung cancer. For those people who smoke two, three or more packs a day, statistics show that one in seven diagnosed will die from the disease. Cigarette smoking is not the only culprit to lung cancer. Cigar smoking and pipe smoking can also lead to the disease at a lower rate. Those who smoke cigars or pipe smoke are five times more likely to get lung cancer than a person who never smoked.

The smoke found in tobacco has over 4,000 element compounds. Many of these are cancer causing. Two key carcinogens are polycyclic aromatic hdrycarbons and nitrosamines. Once a person has given up tobacco use, lung cancer risks decreases every year. Normal cells will begin to grow and outnumber damaged lung cells. After 15 years of not smoking, lung processes and the threat of the disease gets close to that of someone who has never smoked.

Passive Smoking – What is passive smoking? This is when people who are in close quarters smokers breathe in the smoke filled air. Those who don’t smoke have a 24 percent likelihood to develop lung cancer if they live with a smoker. Nearly 3,000 deaths can be associated with passive smoking.

Asbestos Fibers – Mesothelioma and lung cancer through asbestos exposure is high. People who work in asbestos related fields and smoke dramatically increase their chances of getting a lung cancer connected disease. When compared with their non smoking counterparts, they have a 50 to 90 percent greater risk of getting lung cancer or other lung related illness.

Radon Gas – Radon gas has been documented to be the next leading cause in lung cancer deaths, killing anywhere from 15,000 to 22,000 people in the United States every year. Like asbestos exposure, radon exposure augments lung cancer risks. The gas is able to travel through soil. It can gain entrance into homes by the gaps found in its foundation, its drains and its pipes. Nearly one in 15 homes is found with dangerous level of radon gas according to the United States Environmental Protection Agency. Can a person tell if their home has high amounts of radon gas? Only by a kit. The gas cannot be smelled, nor can be it seen.

Genetics – It’s true that most cases of lung cancer can be linked back to smoking. However, not every smoker will get the disease. That means other factors like genetics could play a part behind the causes of lung cancer. Studies have revealed that cancer can and does occur in families that have smokers and nonsmokers. It would seem a gene can increase the vulnerability of smokers in getting lung cancer.

Lung Diseases – When a smoker or even non smoker has other lung diseases such as COPD (chronic obstructive pulmonary disease), they are at an increased risk to develop the disease even if they quit smoking and all the effects have worn away.

History of Lung Disease – People with a record of lung cancer are at a higher risk of developing it a second time. People who have survived a non-small cell lung cancers have a one to two percent risk to getting the disease a second time while those who have beaten small cell lung cancers have a six percent increase each year.

Air Pollution – The chances of getting lung cancer from air pollution is raised in individuals that breathe in polluted air every day. Pollution from cars, power plants and industrialized areas increases these risks. Yet, they only account for one percent of lung cancer related deaths. Experts have suggested that every day exposure to air heavily polluted can be compared to passive smoking.

Can you get lung cancer from smoking weed?

February 21st, 2010

A new study suggests no, there have never been any reports indicating that someone has gotten lung cancer from weed.

“May 23, 2006 — People who smoke marijuana do not appear to be at increased risk for developing lung cancerlung cancer, new research suggests.

While a clear increase in cancercancer risk was seen among cigarette smokers in the study, no such association was seen for regular cannabis users.

Even very heavy, long-term marijuana users who had smoked more than 22,000 joints over a lifetime seemed to have no greater risk than infrequent marijuana users or nonusers.

The findings surprised the study’s researchers, who expected to see an increase in cancer among people who smoked marijuana regularly in their youth.

“We know that there are as many or more carcinogens and co-carcinogens in marijuana smoke as in cigarettes,” researcher Donald Tashkin, MD, of UCLA’s David Geffen School of Medicine tells WebMD. “But we did not find any evidence for an increase in cancer risk for even heavy marijuana smoking.” Carcinogens are substances that cause cancer.

Tashkin presented the findings today at The American Thoracic Society’s 102nd International Conference, held in San Diego.Boomers Reaching Cancer Age

The study population was limited to people who were younger than 60 because people older than that would probably not have used marijuana in their teens and early adult years.

“People who may have smoked marijuana in their youth are just now getting to the age when cancers are being seen,” Tashkin says.

A total of 611 lung cancer patients living in Los Angeles County, and 601 patients with other cancers of the head and neck were compared with 1,040 people without cancer matched for age, sex, and the neighborhood they lived in.

All the participants were asked about lifetime use of marijuana, tobacco, and alcohol, as well as other drugs, their diets, occupation, family history of lung cancer, and socioeconomic status.

The heaviest marijuana users in the study had smoked more than 22,000 joints, while moderately heavy smokers had smoked between 11,000 and 22,000 joints.

While two-pack-a-day or more cigarette smokers were found to have a 20-fold increase in lung cancer risk, no elevation in risk was seen for even the very heaviest marijuana smokers.

The more tobacco a person smoked, the greater their risk of developing lung cancer and other cancers of the head and neck. But people who smoked more marijuana were not at increased risk compared with people who smoked less and people who didn’t smoke at all. ”

Cancer Causing Agents: Tobacco & Nicotine

February 17th, 2010

Smoking is the single biggest cause of cancer in the world, and accounts for one in four cancer deaths in the States. Smoking is known to cause around eighty percent of lung cancer around the world. The 1996 National Household Survey on Drug Abuse has shown that about 62 million people in the United States above 12 years or below 29 percent of the population are current cigarette smokers. So, this makes nicotine, the addictive component of tobacco, one of the most heavily used addictive drugs in the United States. Within the United States, tobacco use was responsible for nearly 1 in 5 deaths or an estimated 438,000 premature deaths per year from 1997 to 2001 & thus, smoking kills five times more people than road accidents, overdoses, murder, suicides and HIV all put together.

Nicotine: Many people believe that nicotine causes cancer but the fact is that it only leads to addiction. Whenever a person inhales cigarette smoke, the nicotine present in the smoke is rapidly absorbed into the blood and its affect on the brain is shown within 7 seconds. In the brain, nicotine activates the same reward system as do other drug abuse such as cocaine or amphetamine, but to a lesser extent. Nicotine acts on this reward system and is believed to be responsible for drug-induced feelings of pleasure and, over time, nicotine addiction. It also increases alertness and enhances mental performance. Studies indicate that nicotine by itself may not be harmful. But, when it is combined with other harmful substances such as areca nut, cancer causing catechu substitutes like gambier & magnesium carbonate, it may show damaging effects.

Apart from nicotine, cigarette smoke contains around 4,000 different compounds, many of which may cause cancer. In fact tobacco smoke contains about 70 different carcinogens or cancer-causing substances. When you inhale smoke, these chemicals enter your lungs and spread around the rest of your body. Scientists have shown that these chemicals are mutagenic & can damage DNA and change expression of various genes which may lead to cancer by making your cells proliferate and multiply uncontrollably. No wonder, smoking is the major cause of lung cancer and is also associated with the increased risk for cancer of the mouth, nasal cavities (nose), larynx (voice box), pharynx (throat), esophagus (swallowing tube), stomach, liver, pancreas, kidney, bladder, uterine cervix, and acute myeloid leukemia.

Oral tobacco products contain 28 known cancer-causing agents (carcinogens). Chewing tobacco is a known cause of oral cancer & according to Women’s Health in South East Asia (WHOSEA), almost one-half of all cancer cases in men and one-quarter of all cancer cases in women in India are believed to be tobacco-related.

Not all smokers get cancer: Years of research has proven that smoking causes cancer but this doesn’t mean that all smokers will definitely get cancer or that all non-smokers won’t. It means that smoking greatly increases the risk of cancer & Smokers are, on average, much more likely to get cancer than non-smokers.
