Will lung cancer be passed on to the next generation? A brief introduction to the genetic factors of lung cancer

In life, when you see someone with lung cancer, don't hide or be afraid, because lung cancer is not contagious. However, experts say that lung cancer is hereditary. In order to avoid this problem, we must take precautions, and timely detection and early treatment are also key. Experts have introduced the genetic issues of lung cancer to us, and you can pay attention to them:

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. Infection is 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.

Only by understanding the disease can we take targeted prevention measures, stay away from high-risk groups, and avoid pathogenic factors, which can reduce the incidence rate. Improving immunity, exercising more, maintaining a good psychological quality, and not smoking or drinking can help us stay away from lung cancer. People with respiratory diseases should pay more attention to the incidence rate of lung cancer.
