Nowadays the factors which may lead to lung cancer are rather numerous. Still some of them are regarded as the most typical lung cancer risk factors.
Usually smoking is regarded as one of the main causes of lung cancer, amounting 80 percent of all lung cancer cases. The risk grows due to how long and how much a person has been smoking, whether the smoke is inhaled or not. But still a person could prevent the development of the disease by quitting. Then the lung tissue can, though rather slowly, return to normal state, which reduces the risk of getting lung cancer.
Besides, those who smoke could expose non-smokers to the risk of getting lung cancer. Passive or involuntary smoking, known as well as secondhand smoke or environmental tobacco smoke, increases the possibility of getting the disease and thus is no less dangerous than simple smoking.
The other factor, which makes the risk of getting lung cancer higher, is heat-resistant fibrous silicate mineral, called asbestos. Asbestos could fall to particles, which stay in the air and could easily get in the lungs, injuring cells and thus being a potential danger and cause for lung cancer development. In earlier times asbestos was used as fireproof insulating materials, but after discovering its dangerous influence it’s rarely used in home products or in workplace nowadays.
Those workers who have been involved in shipbuilding industry, asbestos mining and manufacturing, insulation work, or the others industries, where asbestos is used, have a rather high risk to get lung cancer. viagra online canada
In addition to smoking and asbestos, radon, a radioactive gas without a smell and colour, is regarded as a risk factor for lung cancer as well. Radon harms the lungs, which could also lead to the disease. Usually mine-workers are exposed to this radioactive gas, and thus have a very high possibility to get lung cancer. In homes the level of radon may be controlled by a kit.
The
development of lung cancer may be caused by some other diseases, which damages
the lungs. For example, those, who suffer from tuberculosis or have had some
types of pneumonia, have the risk to get lung cancer. Furthermore, lung cancer
may be also caused by family predisposition to this disease. Those, who have
once suffered the disease, have the risk to get lung cancer again.
