Can gastric cancer be transmitted to others? Gastric cancer has become a malignant tumor disease that seriously affects human health and life in today's society. It not only brings great pain to patients, but also makes their families feel extremely heartbroken. Many people have a question in their lives: Is the high incidence of gastric cancer contagious? Let us learn about the relevant content below.

Experts point out that gastric cancer is not like other germs that can be transmitted from one person to another. Even if sexual intercourse occurs, it will not be transmitted to another person through sexual contact. The reason is simple. Cancer is not an infectious disease. It cannot transmit oncogenes into other people's bodies through any means to cause cancer. Even if cancer cells are implanted into other people's bodies, they cannot survive. Because to oneself, other people's cancer cells are a kind of foreign body. The body can kill other people's cancer cells through its powerful immune rejection ability. Therefore, it can be absolutely said that gastric cancer is not contagious. The simplest reason is that tumors are not infectious diseases. It cannot transmit oncogenes into other people's bodies through any means to cause tumors. Even if tumor cells are transplanted into other people's bodies, it is difficult for them to survive because of the existence of rejection reactions.

However, some people may ask, why do some families have more than one cancer patient? This relative clustering of cancer in the family is not caused by infection, but is mainly related to heredity and common carcinogenic factors. The so-called infection, in simple terms, is the transmission of a disease from one person to another through some means.
