Is lung cancer contagious? Analysis on the contagiousness of lung cancer

According to medical surveys, as environmental quality continues to deteriorate, more and more people are suffering from lung cancer. Many lung cancer patients not only suffer from the pain of the disease, but also have to endure discrimination from others, especially in public places, people wearing masks always make people eager to stay away. So, is lung cancer contagious? Now let's take a look at the experts' introduction to whether lung cancer is contagious?

Studies have shown that there are some internal factors that cause lung cancer. Family, genetic and congenital factors, as well as reduced immune function, metabolic and endocrine dysfunction, etc. may also be the cause of lung cancer. In this case, lung cancer has a special "transmission" method - inheritance. 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.
