Can rectal cancer be transmitted by sharing tableware?

Rectal cancer is a lifestyle disease. The incidence of rectal cancer is getting higher and higher, and its mortality rate has also jumped to the forefront. The blood of hemorrhoids is generally bright red, while the blood of rectal cancer is generally darker than that of hemorrhoids; the blood of hemorrhoids is often drop by drop, while the amount of blood of rectal cancer is sometimes more; although the blood of hemorrhoids and rectal cancer is first blood and then stool. So is rectal cancer contagious by sharing tableware?

What is infection? Simply put, it is a disease that spreads from one person to another through some means. Infection must meet three conditions: source of infection, route of transmission and susceptible population, none of which can be missing. Cancer patients themselves are not sources of infection. Cancer tissue removed from cancer patients cannot survive and grow directly on another person. Although it is believed that the occurrence of some cancers is related to certain viruses, such as cervical cancer, nasopharyngeal cancer, and leukemia, it has not been confirmed that infection with certain viruses will definitely lead to certain cancers. At present, the World Health Organization has not listed cancer as an infectious disease, and cancer patients are not isolated like infectious diseases. The incidence of cancer among medical staff in tumor hospitals is not higher than that of the general population. Animal experiments have verified that cancerous animals and healthy animals have been kept together for a long time, and no infection has been found after repeated observation and examination. If family members and friends have cancer, don't worry about infection, but spend more time with them, give them warmth and love, so that the patient can recover soon.
