Oral cancer is generally not contagious, so daily contact with oral cancer patients will not transmit oral cancer, so there is no need to worry too much.
1. Oral cancer is a malignant disease, which does not belong to the category of infectious diseases. Moreover, clinically, an infectious disease must have the three elements of infectious source, means of transmission and susceptible people, while oral cancer as a tumor disease does not have these three elements, so it will not be infectious.
2. The occurrence of oral cancer is related to the triggering factors such as viral infection, long-term heavy smoking and drinking and betel nut chewing etc. Infectious disease is a kind of disease that spreads among different individuals, for example, tuberculosis and influenza, etc. These two categories of diseases are very different from each other.
