Is my mother's stomach cancer contagious?

Gastric cancer is a common disease. There are many people who have this disease. Is gastric cancer contagious? This is a question that everyone is very concerned about. The following editor will explain this issue to you to avoid unnecessary panic.

Gastric cancer is not transmitted from one person to another like other germs, even if sexual intercourse occurs, it cannot be transmitted to another person through sexual contact. Even if cancer cells are implanted into another person's body, they cannot survive.

Because to ourselves, other people's cancer cells are a foreign body, and the body can kill other people's cancer cells through its powerful immune rejection ability.

Therefore, it can be said with absolute certainty that gastric cancer is not contagious. The simplest reason is that tumors are not infectious diseases. They cannot introduce oncogenes into other people's bodies through any means to cause tumors. Even if tumor cells are transplanted into other people's bodies, they are difficult to survive because of the existence of rejection reactions.

Therefore, gastric cancer is not contagious. Because the source of infection, the route of transmission and the susceptible population are all indispensable. Clinical data prove that cancer patients themselves are not the source of infection. Experts have conducted such experiments. Cancerous tissues taken from cancer patients cannot survive and grow when directly implanted in another person. Although it is currently believed that the occurrence of certain cancers is related to certain viruses, such as cervical cancer, nasopharyngeal cancer, and leukemia, it has not yet been confirmed that infection with certain viruses will definitely lead to certain cancers.
