Can lung cancer be contagious? Experts tell us whether lung cancer is contagious

Suffering from lung cancer is a huge blow to the patient. Patients do not have a clear understanding of the disease, and family members are worried that the disease will be transmitted when caring for the patients. We must pay attention to it and understand the condition well. First, let us take a look at whether lung cancer is contagious.

Is lung cancer contagious? Experts say that the reason why people think lung cancer is contagious is because they do not distinguish between lung infectious diseases and lung cancer. Lung cancer is a type of lung disease, but it is not contagious. In simple terms, contagion means that a disease is transmitted 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. Clinical data prove that cancer patients themselves are not the source of infection.

The contagious lung diseases that people know about are mostly "pulmonary tuberculosis". Patients with pulmonary tuberculosis are called open pulmonary tuberculosis when their sputum is positive for bacteria. They are contagious. Therefore, if you encounter a tuberculosis patient who coughs, expectorates, or has blood in his sputum, you should take precautions. Pulmonary tuberculosis is a disease transmitted through the respiratory tract, but lung cancer is different from pulmonary tuberculosis. Lung cancer is a malignant tumor that is caused by the abnormal proliferation of local cells under the action of various different carcinogenic factors and loses its normal cell morphology and dynamics. Cancer cells discharged through sputum rapidly degenerate and necrotize due to the evaporation of sputum water and other reasons. Even fresh sputum requires various nutrients and specific conditions to make cancer cells grow and reproduce in vitro. Scientists often have to go through a lot of hardships to succeed in cultivating a living cancer cell, so cancer is not contagious.

As for whether lung cancer is contagious, we should also distinguish between contagious and hereditary issues. Lung cancer has a certain family history, but it is not contagious. However, we do not need to worry. Lung cancer only has a certain genetic tendency. If it is to develop, it will only occur under the influence of external factors.

Can lung cancer be contagious? After reading the above introduction, I believe patients will understand that we must face the disease bravely in life and go to the hospital for treatment regularly. This type of disease should be detected and treated early, and we should maintain a happy mood.
