Abstract
The prevention and diagnosis of lung cancer in the Chinese population has received extensive attention in past few years. Many studies have suggested that genetic predisposition may be a risk factor for lung cancer and an important means for early diagnosis of carcinoma of the lung. At present, the research on the molecular mechanism of lung cancer has been carried out on the whole genome, and a large number of SNPs have also been found in the Chinese population, these results suggest that the genetic predisposing factors of lung cancer in Chinese population are different from those in foreign population.
