In fact, many people don’t know much about lung cancer and worry about whether lung cancer is contagious. Let us solve this problem for you.

Is lung cancer contagious? The so-called contagion refers to the spread of a disease from one person to another through some means. Contagion must meet three conditions: the source of infection, the route of transmission, and the susceptible population. Without any of them, it cannot be contagious. However, research shows that lung cancer is not a source of infection, so lung cancer is not contagious.

Lung cancer cells are a group of abnormal cells that have lost control and are malignantly proliferating uncontrollably. They not only destroy adjacent normal tissues and organs, but can also spread and metastasize to other parts of the body. Is lung cancer contagious? Although cancer cells can spread or metastasize everywhere in the patient's body, they will not be transmitted from one person to another like bacteria and viruses. To the body, other people's cancer cells are a kind of foreign body, and the body will destroy the cancer cells through its powerful immune rejection ability. Therefore, other people's cancer cells cannot survive in one's body, and lung cancer will not be transmitted to others.

From the perspective of infectious diseases, is lung cancer contagious? Lung cancer is not contagious, but some diseases before lung cancer are contagious, such as tuberculosis, which is a factor that causes lung cancer. Tuberculosis is an infectious disease. So it is not correct to say that lung cancer is not contagious.
