Common Causes of Lung Cancer

There are a few factors that lead to lung cancer. Some of the most common reasons are:

1. Cigarette smoking: It is a very common factor. There are people who are addicted to cigarette smoking and some even smoke two packs or more per day. Out of every seven people, at least one person would develop lung cancer. Folks who smoke about one pack of cigarettes per day are prone to this threat 25 times more than non-smokers. People who casually smoke are also not free from this, as they could also develop lung cancer.
Smoking damages the cells. The moment you quit smoking the damaged cells start repairing themselves and become healthy cells. So, it is advised to give up smoking altogether.

2. Secondhand smoking: it is also known as passive smoking because you tend to inhale smoke without actually holding a cigar or a pipe between your lips. The people who are exposed to this kind of smoking have 24% chances of developing lung cancer. About 3000 deaths are estimated in a year due to secondhand smoking.

Asbestos Exposure: Asbestos causes lung cancer and mesothelioma known as the cancer in the linings of the pleural sheet. It separates the silica fibers that are trapped in the tissues of the lungs. If you have been a smoker or if you smoke even now, then the possibility of contracting this disease is high. The risk is about 50 to 90 percent more than non-smokers.

Radon Gas: radon is a gas that is colorless and odorless that is released from decayed uranium. As per the analysis done by the U.S. Environmental Protection Agency, almost 15% of the homes are exposed to radon and every year about 15,000 to 22,000 deaths occur.

Air pollution: if you inhale polluted air for a long period of time then you are most likely to develop cancer. About 1% of the total lung cancer deaths are due to this problem.

Small Cell Lung Cancer Causes – Difficult To Treat, Survival Rates Are Low

Cancer in the lungs is classified as small-cell or non-small cell carcinoma. Both types are difficult to treat, and survival rates are low. While research in this area has developed promising solutions for futures cures, solid cancer study results emphasize prevention as the best medicine.


Cigarette smokers inhale dozens of carcinogens. Researchers have identified direct contributors to this cancer among them. According to the American Lung Association and the National Cancer Institute, the cessation of smoking and the use of other tobacco products will reduce the chances of developing this cancer.

Exposure to secondhand smoke is a risk factor also. Avoiding smokers and places with high exposure to cigarette smoke aids in preventing the disease. Smokers who quit decrease the chance of getting small-cell carcinoma in the lungs, as well. After cessation of smoking the body begins to heal itself, and after several years the damage is undetectable.

Supplement and Exposure

Beta Carotene is not a direct cause of cancer, but according to studies in the Journal of the National Cancer Institute (December 1, 2004) it enhances the probability of developing the disease. The study showed increased risk for smokers up to six years after taking the supplement during the trial. The trials included smokers, people who quit smoking, and patients exposed to asbestos.

The surgeon general proclaimed that radon gas is the number two cause of cancer in the lungs. People are exposed to this gas when uranium in soil breaks down and releases it. The exposure is greatest in the home, where it gains access through cracks in the walls, floors, or windows. Radon causes cancer when radioactive particles are inhaled, damaging the lung tissue lining. High levels of radon in the home can build up over time. Simple testing will determine if radon levels in the home are too high.

Genetic Anomalies

Studies have demonstrated that patients with genetic anomalies of chromosome 15 have greater tendencies to cigarette addiction, and a higher incidence of lung cancer. Research also points to certain genetic markers with the same result. Solid evidence from major foundations like the National Health Institute agree that not smoking is the best way to avoid developing lung cancer.

I for one know there’s a ton of lung cancer information scattered all around the web, and I know it can be somewhat depressing to go through much of it. I have compiled all that researched so it might benefit others. I put many months of research into a useful guide. There’s no charge of course and I think you’ll appreciate the simplicity of it. Its at While you are there, you’ll find this article about Lung Cancer Causes and many other very straight forward, helpful articles.

Air Purifers: The New Bottled Water

Imagine all the garbage in the air that we are forced to breathe in from industrial processes, smog, car pollution, aerosols, etc, then processing all that in our overworked lungs, and breathe back out to the environment again, is there any chance we can find a moment’s solace with clean, fresh, and healthy air the way mother nature intended it to be? Not unless you lived on a deserted island.

I don’t know about you, but with the rate of pay from my job I don’t think I will be purchasing my own island any time soon. But that doesn’t mean I don’t want to breathe clean air, much like I drink clean bottled spring water at the drop of a dime. If you think about it, those two things are quite common in our everyday lives and are required for functioning and health reasons. Bottled water has pretty much provided us with an alternative way to have clean pure water. Shouldn’t air purifiers also be considered a must have in our polluted environment? Not convinced?

Here is a quick run down on 5 categories of pollution that is common in the typical household alone:

1. Odor. This comes from food, animals, body odor, cigarettes, stinky sneakers, clothing, equipment, and others.

2. Particulate. On a nice sunny day, you pull up your shades and are just about ready to take a big whiff of fresh air, but you notice little particles everywhere visible via the suns rays and you stop yourself in your tracks. Those are particulates and to the naked eye one cannot see that it consists of many things including dust, dust mites, dust mite fecal matter, animal dander, skin flakes, pollen, smoke, and allergens.

3. Microbials. These include bacteria, fungi, mycotoxins, mildew, viruses, and mold spores.

4. Chemical Fumes. Benzene and formaldehyde are two examples, these fumes are persistently seeping from carpets, upholstery, draperies, furniture, cleaning products, beauty products including nail polish and polish removers. Additionally fumes can be found in cigarette, pipe and cigar smoke, as well as from the building construction of your home or apartment. Many of such chemicals have been identified as carcinogenic (cancer causing).

5. Radon Gas: Second leading cause of lung cancer. Radon is for all intents and purposes invisible to the naked eye, nose, and what have you. Radon is enhanced by smoking.

Now that you have some knowledge of the pollution that is inescapable in our daily lives, it is perhaps time to treat clean air as vitally important as clean water.

Are Non-Smokers Vulnerable to Lung Cancer?

Lung cancer (LC) has traditionally been considered a smoker’s disease. That is, the illness’s impact is thought to be reserved to those who habitually smoke. To be sure, of the nearly 180,000 cases that are diagnosed each year, most are attributed to the use of cigarettes.

Having said that, it is estimated that up to 15% of diagnosed cases occur in those who do not smoke. In this article, we’ll explore the issue of non-smokers suffering from lung cancer. We’ll explain the reasons it can happen and potential risk factors that make some people more susceptible than others.

Reasons The Disease Impacts Non-Smokers

Among all of the factors that contribute to non-smokers developing the disease, secondhand smoke is the most common. According to, nearly 38,000 people die each year from secondhand smoke. Cigarette smoke contains over 4,000 chemicals. Being exposed to these chemicals over an extended period of time can lead to the development of tumors.

Another potential cause of LC in those who do not smoke is prolonged exposure to radon gas. In fact, the U.S. Environmental Protection Agency (EPA) lists radon gas as the second leading cause (after smoking) of the growth of cancerous cells. The EPA further estimates that one in fifteen homes in the U.S. contain dangerous levels of radon gas.

Exposure to asbestos fibers can also cause the disorder. Decades ago, asbestos was used liberally in the insulation within homes and buildings. The fibers can penetrate the lungs and remain there for a lifetime. It is estimated that those who work with asbestos and do not smoke are five times more likely to suffer lung cancer than nonsmokers.

Other Potential Risk Factors

Besides smoking, passive smoking (i.e. long-term exposure to secondhand smoke), radon gas, and asbestos fibers, non-smokers can also be predisposed to developing lung cancer. For example, researchers suspect there is a particular gene within chromosome number 6 that increases a patient’s susceptibility to the disease. Ethnicity and family history are also thought to play a role.

If you suspect you have LC, see your doctor immediately. It is important to diagnose and treat the disease before the cancerous cells have metastasized to other parts of your body.

Your doctor will take X-rays of your chest to identify areas in which cancerous cells may exist. He or she may also order a computerized tomography (CT) scan to examine suspect areas in more detail. An MRI may be done to help identify the location of tumors once lung cancer has been diagnosed. Bone scans can also be performed to determine the extent of metastasis.

The next step is to stage the disease. It is through staging that your physician will determine how far the cancer has advanced and the appropriate form of treatment. He or she will then recommend a treatment program that might include surgery, chemotherapy, and radiation therapy. The sooner treatment begins, the higher likelihood for survival.
