Can kiss of lung cancer infect

First, cancer is generally not contagious. The so-called infection, in short, is a disease from one person through a certain way of transmission to another person. There are three conditions for infection: source of infection, route of transmission and susceptible population. Clinical data show that cancer patients themselves are not the source of infection. So instead of avoiding lung cancer patients, we should pay more attention.

Second: pulmonary tuberculosis is a disease transmitted through respiratory tract, and lung cancer is different from pulmonary tuberculosis. Lung cancer is a malignant tumor with abnormal proliferation of local cells and loss of normal cell morphology and dynamics under the action of various carcinogenic factors. Due to the evaporation of water in sputum, the cancer cells discharged from the sputum degenerate and die rapidly. Even if the fresh sputum is used to make the cancer cells grow and reproduce in vitro, it also needs to give a variety of nutrients and specific conditions. In order to cultivate a living cancer cell, scientists often have to go through a lot of hardships to succeed, so cancer is not contagious.

Third: Although cancer cells can spread or metastasize everywhere in patients, it will not be like bacteria and viruses, and lung cancer will not be transmitted from one person to another. To oneself, the cancer cell of others is a kind of foreign body. The body destroys the cancer cell through its strong immune rejection ability. Therefore, other people's cancer cells can not survive in their own body.
