How does lung cancer spread

summary

There is an uncle who is over 60 years old. He usually has no health problems, but he has some stomach problems. But when I went to see him this year, I said that he was suffering from gastric cancer and was being treated in the hospital. Now his condition has been controlled to a certain extent. I'll tell you how lung cancer is transmitted.

How does lung cancer spread

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 sources of infection and three routes of transmission. 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.

matters needing attention

Cancer is not contagious, so lung cancer is not an infectious disease, tuberculosis is a very serious infectious disease, but lung cancer is different from it, there is no infectious, so do not worry about being infected, and to live in harmony with lung cancer patients, more care for lung cancer patients.
