Can stomach cancer be transmitted through kissing?

With the continuous development of society, people's lifestyles and eating habits have undergone tremendous changes. At the same time, due to the added pressure of social competition, more and more people are suffering from gastric cancer. The mortality rate of gastric cancer ranks first among other malignant tumors. It can be seen that the threat posed by gastric cancer to people's lives and health is very serious. So can gastric cancer be contagious by kissing?

Due to the prevalence of gastric cancer, people can't help but ask: Is gastric cancer contagious?

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.

Is gastric cancer contagious? First of all, we need to know the conditions for contagion. Contagion must meet three conditions: the source of infection, the route of transmission, and the susceptible population. None of the three can be missing. Clinical data proves that cancer patients themselves are not the source of infection.
