Eating with cancer patients can be contagious?

Cancer is not an infectious disease, and cancer cells in cancer patients are

not infectious, so eating with cancer patients is generally not infected, so there is

no need to worry too much about it. If liver cancer or stomach cancer patients, especially those related to hepatitis virus infection or Helicobacter pylori infection, pathogens may be infectious and spread orally, but cancer itself is not infectious, and infection with these pathogens may not necessarily cause cancer.
