Can lung cancer be contagious to humans?

Lung cancer is not contagious, but it is important to note that it is hereditary. For lung cancer, two aspects must be achieved. First, it needs to be cured in a timely and thorough manner, and prevention is necessary. However, prevention must grasp the key factors. The following is a specific introduction to the genetic issues of lung cancer:

Lung cancer is a hereditary disease. People with a family history of lung cancer are more likely to develop lung cancer than normal people. Although lung cancer seems to have a familial clustering phenomenon, there is no evidence to date that there are specific susceptibility genes for lung cancer.

More and more studies support that lung cancer is caused by the interaction between genes and the environment. Genetic variations in carcinogen metabolism, DNA repair, and cell proliferation and apoptosis control genes may be important genetic susceptibility factors for smoking-related lung cancer. Therefore, the key measure to prevent and reduce the occurrence of lung cancer is to quit smoking.

But we need to understand that heritable diseases do not necessarily mean they will be inherited. Infections are infectious diseases caused by the spread of microorganisms, including bacteria and viruses, between people, such as tuberculosis and hepatitis. Heredity is due to blood ties, causing many people in a family to suffer from the same disease. If one of the parents suffers from a certain type of cancer, their children are more likely to suffer from the same type of cancer, which means that cancer patients often have a clear family history of tumors.

The survey results show that the incidence rate of cancer patients is higher among blood-related patients than among unrelated patients, and higher among close relatives than among distant relatives, while there is no obvious difference between paternal relatives and maternal relatives, indicating that the incidence of cancer is related to genetic factors.

We should have enough knowledge about lung cancer, a highly prevalent malignant tumor, and try to avoid possible high-risk causes in life, which can reduce the incidence of the disease. We should also pay attention to improving the body's immunity. It should be noted that improving the body's immunity is the basis for preventing any disease.
