What cancer infection?

There is no clinical transmission of cancer.

Cancer is caused by abnormal proliferation of normal cells in most cases. It is not an infectious disease and is not infectious. However, some carcinogenic factors may be transmitted, such as Helicobacter pylori can be transmitted through the digestive tract. Infection with Helicobacter pylori can increase the incidence of gastric cancer. Hepatitis B virus can be transmitted through sexual contact, blood and blood products, and mother-to-child transmission. Hepatitis B virus infection can increase the incidence of liver cancer.

Therefore, when patients are infected with these carcinogenic factors, they should be treated in time to reduce the incidence of cancer.
