The number of people who die from lung cancer is astounding. In America alone, approximately lung cancer has been the cause of deaths of about 20,000 people. Natural instincts will direct you to avoid exposure to tobacco or its products however, there are other risk factors. With much input from advanced technology, researchers are able to piece together other factors that can cause one to develop lung cancer:

Radon gas

The environmental protection agency says that this is the leading cause of lung cancer in nonsmokers. This product is everywhere in our environment and is rather harmless. However, radon is a radioactive substance derived from uranium breakdown which is concentrated in mines and some houses, and continuous exposure is lethal.

Since radon is colorless and odorless, the only way to know if you’ve been poisoned is to get a radon test kit. Moreover, experts recommend a quality easy-to-use home kit which can detect extremely high levels of radon.

Secondhand smoke

Passive smoking causes close to 35% of all lung cancer cases in nonsmokers. There are two types of passive smoking: sidestream smoke where you inhale smoke from the lighted end, and mainstream smoke from the smoker.

Luckily, efforts are being put to stop lung cancer from secondhand smoke: this is why smoking in some public areas has been banned. Some people are more susceptible to develop lung cancer from secondhand smoke than others, such as those exposed to it when they were still children.


Asbestos is a mined material found in many building materials and cars. It is resistant to fire and is common in many construction industries. Because more people are aware of the risk it has in development of lung cancer, not many people use it nowadays.

However, you are at risk if you work at companies where asbestos is the main raw material such as roofing companies. Nevertheless, the contribution of asbestos is not much a threat compared to previous days.

Air pollution

There is unending pollution from car exhaust, industries, wood stoves and other sources which increase the risk of developing lung cancer. In the U.S., the clean air act has decreased air pollution and thus lung cancer, although this is still a major problem in other countries like China.

Chest radiation

People who have had repetitive encounters with chest radiations are at risk of getting lung cancer, even if they have never smoked. According to Dr. Lam, women or younger patients who had previous chest radiations increase the risk of getting lung cancer though this is not so common.

Genetic mutations

In as much as there are genetic differences in the way lung cancer tumors present in people who smoke or have never smoked, researchers find that genes are not identical for every individual. Some genes are inherited, and this explains why lung cancer is predominant in some families, or acquired in someone’s lifetime.

A study by the World Health Organization revealed that a larger percentage of people worldwide cook using solid fuels (coal, wood) or use an open flame for the same. With such methods of cooking plus poor ventilation, more pollutants get trapped within households which can contribute to lung cancer.

Women and children are largely affected by lung cancer from indoor pollution because of the time spent while cooking and proximity to such equipment. Therefore, it can explain why there is a lot of indoor pollution in rural areas across the world, and the prevalence of lung cancer.

Prevention of lung cancer

If you have never smoked, the best thing you can keep off lung cancer is to stay that way. If you smoke, perform a radon test at your home and ensure you have safe work standards in a high-risk industry. For people who have a high chances of developing lung cancer, are above 55 years and smoke often, CT screenings are recommended for lung cancer screening.

However, the rest of the population that is healthy should not get screened since the risks are more than the benefits. As stated earlier, radiations increase the risk of lung cancer, and some might get a wrong positive reading – the test indicates cancer. Give priority to your diet.


There is evidence that a healthy diet filled with fruits and vegetables can prevent lung cancer.
