Is tuberculous lung cancer contagious?

The incidence of cancer has grown rapidly in recent years, which has made many people worried. There are many types of cancer, among which lung cancer is one of them, and its incidence is also very high, and its mortality rate is also ranked first among malignant tumors. Many friends will ask, is lung cancer contagious? Let's explore this question together.

Is lung cancer contagious? Studies have shown that lung cancer is not contagious, but its hereditary nature cannot be ignored. Clinical surveys show that among lung cancer patients, the incidence of blood-related patients is much higher than that of unrelated patients, 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.

Is lung cancer contagious? Studies have also shown that there are some internal factors that cause lung cancer, such as family, genetic and congenital factors, as well as reduced immune function, metabolic and endocrine dysfunction, which may also be the cause of lung cancer. In this case, lung cancer has a special transmission method. Families of lung cancer patients should pay attention to prevent the possibility of lung cancer.

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.
