Can gastric cancer saliva be transmitted to humans?

Gastric cancer is a common disease. We often meet people with this disease. Will they infect us? This is a question that everyone is very concerned about. Here, I will explain the question of "Can the saliva of gastric cancer patients infect others?" to avoid unnecessary panic.

Can the saliva of a stomach cancer patient infect other people? Experts suggest that stomach cancer is not like other germs that can be transmitted from one person to another, and even if sexual intercourse occurs, it cannot be transmitted to another person through sexual intercourse. Therefore, the saliva of a stomach cancer patient cannot infect other people. 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.
