Is lung cancer contagious? Here are three things you must know about lung cancer

People's living standards are improving year by year, and the types and incidence of diseases are getting higher and higher. In recent years, the number of people suffering from lung cancer in my country has increased, and people's attention to lung cancer has also increased day by day. So, how much do you know about lung cancer? Is lung cancer contagious? Let's take a look at the following introduction.

First, transmission, in simple terms, is a disease that is transmitted from one person to another through a certain medium. For transmission to occur, there must be three conditions: a source of infection, a transmission route, and a susceptible population. Without any of these conditions, transmission is impossible. According to clinical evidence, cancer patients themselves are not sources of infection, so cancer is not contagious.

Second, the patient develops cancer under the influence of multiple carcinogenic factors, causing the local cells of the body to proliferate abnormally, losing the dynamic balance and morphological performance of normal cells, and eventually forming a malignant tumor. Cancer cells discharged through sputum will quickly degenerate or necrotize due to factors such as water evaporation. Even cancer cells in fresh sputum will not grow and reproduce without certain nutritional supply and specific conditions. Therefore, the infectiousness of lung cancer cannot be established.

3. In animal experiments, animals with tumors will not directly infect animals without tumors. Regarding the problem of malignant tumors appearing one after another in family members, this may be related to the fact that family members share genes or are in the same carcinogenic environment, such as being exposed to certain radioactive substances or smoking, and has nothing to do with cancer itself.

I believe that after reading the above introduction, everyone has a deeper understanding of lung cancer. In fact, we only talk about many diseases but we have not really understood them. Lung cancer is a very harmful disease. Experts hope that everyone can do more prevention and patients should also do corresponding care to get rid of the suffering of lung cancer.
