People with cancer genetic predisposition are more likely to get cancer than others. A survey report in the United States pointed out that in 6 1 families with breast cancer tendency, nearly half of mothers have breast cancer, and their daughters also have breast cancer, and the onset age is young, and the disease develops rapidly and seriously; Non-smokers with a family history of lung cancer are four times more likely to cause cancer than non-smokers without a family history of lung cancer. However, smokers with a family history of lung cancer are 14 times higher than the general population.
A reader once asked, if his father has cancer, will he and his brothers also get cancer? The answer is not to be too nervous. Some scientists have pointed out that precancerous lesions can only occur if there are as many as 10 or more gene mutations in a key gene before the cell becomes cancerous, but only one gene mutation cannot completely cause cancer. Therefore, congenital gene mutation can only make offspring have genetic tendency, and the key is the invasion of acquired environmental carcinogens, which will lead to cancer. Therefore, avoiding all environmental carcinogens is the key to prevent cancer.
