summary

We all know that cancer is a terrible disease, but we don't know if it will be contagious. Unfortunately, my classmates found that they have lung cancer, which may be caused by too much smoking. Fortunately, it is early. Now let's popularize science to see if lung cancer patients are infectious.

Is lung cancer contagious

First, there are four ways for cancer cells to metastasize, namely, direct spread, lymphatic metastasis, hematogenous metastasis and implantation metastasis. In general, it will not be infected by normal skin contact. However, when the skin is damaged, the cancer cells will be planted. In this way, the cancer cells will metastasize rather than infect others. So there is no evidence that lung cancer is contagious.

Second: can lung cancer infect people? Cancer will not infect under normal circumstances, and there must be three conditions for infection: source of infection, route of transmission and susceptible population. These three conditions are indispensable, so it is generally not contagious. Most people think that tuberculosis is lung cancer. In fact, it's not the same. Although all of them are lung diseases, lung cancer is not infectious.

Third: 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.

matters needing attention

First of all, we can rest assured that lung cancer will not be contagious, but it will do great harm to the health of patients. The earlier treatment, the better. Otherwise, the worse the condition will be, the unimaginable consequences will be. Patients should also maintain an optimistic attitude and actively cooperate with doctors for treatment, I believe they can recover as soon as possible.
