Is lung cancer contagious? These common sense can explain the contagiousness of lung cancer

Lung cancer is a common disease in clinical practice, and the severity of this disease cannot be ignored. Many people believe that lung cancer is contagious, but experts have discovered through research that all cancers are not contagious. The pathogenesis is due to the abnormal growth of local tissue cells, so lung cancer is not contagious either. Therefore, there is no need to worry too much about the problem of infection.

Lung cancer is a common malignant tumor in clinical practice. Once it occurs, it will cause great harm to human health, especially for patients with advanced lung cancer, who will lose the best treatment opportunity and their lives will be in danger. Some people in life are also worried about the contagion of lung cancer, and they are often worried. However, through scientific research: lung cancer is not contagious. Let's take a closer look at some of the knowledge.

Is lung cancer contagious? Through years of medical research at home and abroad, it has been found that cancer is caused by the canceration of one's own tissues, so all cancers are not contagious. Specifically speaking, the cancer cells in lung cancer patients and other cancer patients are abnormal cells that have lost tissue control and grow in an invasive manner in local tissues. Its impact is very large. It not only destroys adjacent normal tissues and organs, but also can be transferred to all parts of the body through lymphatic channels and blood circulation, and absorb a large amount of nutrients, grow and proliferate rapidly, leading to systemic failure of the patient and even death.

When various diseased cancer cells reach a certain level in the patient's body, they will spread or metastasize. However, cancer cells will not be transmitted from one person to another through indirect contact or close contact like bacteria, viruses, parasites and other pathogens. To the self, cancer cells in other people's bodies are a kind of foreign matter. In time, the body will destroy other people's cancer cells through its strong immune rejection ability after contacting the patient's cancer cells. Therefore, other people's cancer cells cannot survive in one's own body.

I believe that everyone knows why cancer is not contagious after reading this, but we should also note that although cancer is not contagious, some patients' own diseases, such as patients with viral hepatitis who develop into liver cancer, are easily contagious because of primary liver disease caused by viruses. Therefore, when caring for these patients, we should avoid viral infection.
