It is renowned that a number of cancers, like ovarian cancer and colon cancer, run in families. Although the role of genetic in cancer of lung is not as well-known, having a family history of the disease does raise our risk to some degree. Genetic lung cancer is higher in women, nonsmokers and individuals with early onset the cancer. Taken as a whole, it has been predicted that 1.7% of cancers of lung up to the age of 68 are hereditary.

Lung cancer is the third most common type of cancer identified in the United States and is the primary cause of death in the United States and in the world. While it is recognized that smoking leads to cancer of lung, there are individual differences in vulnerability to lung carcinogens.

Smokers who develop lung cancer are less probable to suffer a family history than nonsmokers that develop the cancer. However, that said, for individuals who have a genetic predisposition to the cancer, smoking comes out to strengthen that risk.

However, Genetics also play a significant role in the development of this deadly disorder. It's likely for heavy smokers to stay cancer free during their lives, while non-smokers can still develop lung cancer because of their genetic makeup.

If you realize that you're genetically predisposed to cancer of lung, the most effectual measure of prevention is not smoking cigarettes. Other measures to stay healthy also could reduce your risk. These encompass eating a balanced diet to keep cells healthy, in addition to exercising regularly, and keeping away from air pollution and secondhand smoke.
