Don't be afraid of lung cancer patients

Many people have little knowledge about lung cancer, and some even think that lung cancer is contagious. Now let's explain whether lung cancer is contagious from the perspective of disease transmission. Some people may also ask, is lung cancer contagious?

Is lung cancer contagious? Cancer cells in the patient's body are a group of abnormal cells that have lost control and grow in an invasive manner. They not only destroy adjacent normal tissues and organs, but can also spread to all parts of the body through lymphatics and blood circulation, absorb a large amount of nutrients, grow and proliferate rapidly, and cause the patient's body to fail and eventually die.

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 oneself, other people's cancer cells are a kind of foreign body. Therefore, other people's cancer cells cannot survive in one's own body.

From the perspective of the macro environment, this may be related to the improvement of medical conditions in urban and rural areas, the fact that tuberculosis patients can receive powerful anti-tuberculosis drugs, the significant reduction in the mortality rate of tuberculosis patients, and the aging of tuberculosis patients. At the same time, factors such as environmental pollution, smoking, and reduced immune function also increase the chance of lung cancer.

I believe that the above content has provided a good answer to the question of whether lung cancer is contagious. For more information about lung cancer, please refer to other content on this website.
