GENETIC FACTOR IN LUNG CANCER
By Antin. Besides smoking (active and passive smoking) as primary cause of lung cancer, there are several things that have connected to lung cancer. Asbestos fibers, radon gas, and air pollution can be the causes of lung cancer. Genetic or familial predisposition may play a role as a cause of lung cancer. Lung diseases and prior history of lung cancer also give someone a greater to get lung cancer / secondary lung cancer.
Although the majority of lung cancers are associated with tobacco smoking, the fact shows that not all smoking people develop lung cancer. It suggests that other factors, such as genetic factors, may play a role in the causation of lung cancer. Numerous studies have shown that lung cancer is more likely to occur in both smoking and nonsmoking relatives of those who have family history of lung cancer than in the general population. Recent research has localized a region on the long (q) arm of the human chromosome number 6 that is likely to contain a gene that confers an increased risk to the development of lung cancer in smoking.
