Lung cancer is not hereditary, but can be affected by genetic factors. Lung cancer is not a hereditary disease, therefore, if parents suffer from lung cancer, it is not necessarily passed on to the next generation, only that lung cancer is also affected by hereditary factors. That is to say, if there are lung cancer patients in one’s family, especially in one’s immediate family, then the chance of one’s children suffering from lung cancer will be increased, which is a high-risk group, but it is not a 100% disease. For people with high risk of lung cancer, it is recommended to have regular lung checkups every year so as to detect lesions in time, diagnose and treat the disease early, and control the disease effectively so as not to jeopardize one’s life.
