It has been found out whether lung cancer is contagious. It is better to know these common knowledge about lung cancer as early as possible

According to the survey, people are causing more and more harm to nature, which means that the current environment is getting worse and worse. Therefore, the incidence of lung cancer is increasing significantly. Now many people have a question about lung cancer, that is, is lung cancer contagious? Let the experts answer it for us.

Studies have shown that there are some internal factors that cause lung cancer, including family, genetic and congenital factors, as well as reduced immune function, metabolic and endocrine dysfunction, etc. In this case, lung cancer has a special transmission method - genetics, and the families of lung cancer patients should pay attention to prevent the possibility of lung cancer.

In fact, lung cancer is not contagious, but its hereditary nature cannot be ignored. Clinical surveys show that among lung cancer patients, the incidence of patients with blood relations is much higher than that of patients without blood relations, and the incidence of close relatives is also higher than that of distant relatives. In order to effectively prevent the occurrence of lung cancer, if people have a family history of lung cancer, they need to undergo regular examinations in a timely manner and take relevant protective measures to achieve early detection and early treatment. This is what friends with lung cancer should pay attention to.

Although lung cancer has a familial hereditary phenomenon, it has not yet been proven that there are specific susceptibility genes for lung cancer itself. It is generally accepted that the combined effects of genes and the environment lead to the occurrence of lung cancer. Genetic lesions are controlled by DNA repair, carcinogen metabolism, and cell proliferation and apoptosis. These may be genetic susceptibility factors for lung cancer related to smoking.

After listening to the experts' introduction, everyone should know that lung cancer is not contagious. Therefore, when there are lung cancer patients around us, we don't have to worry about the problem of contagion. At the same time, I hope everyone can give more care to lung cancer patients and help them recover as soon as possible.
