Lung cancer at the age of 60 is not usually hereditary, but the chances of offspring developing lung cancer may be relatively high. Lung cancer has more causative factors, such as smoking, irritating gases, drugs, etc. Lung cancer is not hereditary, nor is it contagious. However, due to the similar living and dietary habits of family members, lung cancer has a certain degree of family aggregation and genetic susceptibility, resulting in a higher risk of cancer in the patient’s immediate family members than in normal people. It is recommended that the patient’s immediate family members should have regular medical checkups, improve lung CT and tumor markers to screen whether there is space occupation in the lungs, etc. In addition, they should quit smoking and limit alcohol, develop good living habits, and exercise properly to strengthen their physical fitness.
