Can lung cancer be transmitted to others? Introduction to the infectiousness of lung cancer

Lung cancer is a common disease in our daily life. However, many people still do not have a scientific understanding of the infectiousness of lung cancer. Some even think that it can be transmitted through close contact, and they are terrified. So, can lung cancer be transmitted to others? Let's listen to the explanation of relevant experts.

Lung cancer is a respiratory disease, but it is different from influenza and tuberculosis. Influenza is caused by viral infection, and influenza viruses are often transmitted to others through contact with other people. Tuberculosis is caused by infection with Mycobacterium tuberculosis. When Mycobacterium tuberculosis is inhaled by a normal person and reaches the lungs, when the resistance is very low, tuberculosis will occur. Lung cancer is different from influenza and tuberculosis. There are detached cancer cells in the sputum of lung cancer patients, but these cancer cells are not very viable and will quickly rupture and die outside the body, so lung cancer is not contagious.

In hospitals, no one living in the same room with lung cancer patients has been found to be infected with lung cancer, and no nurses who have been in contact with lung cancer patients for a long time have been found to be infected with lung cancer, which also shows that lung cancer is not contagious to others. Therefore, people who often come into contact with lung cancer patients and people who live with lung cancer patients do not have to worry about being infected with lung cancer.

How contagious is lung cancer? I believe that through the detailed introduction of the above experts, everyone has a certain degree of understanding. Here we also remind everyone that once you have lung disease, you must not ignore it and should go to a regular hospital for treatment in time to avoid missing the best time for treatment and delaying the disease.
