Is lymphoma not contagious?

Is lymphoma not contagious? Lymphoma is caused by factors such as people's long-term unreasonable diet structure and irregular living habits, which lead to excessive acidification of the body, a rapid decline in the overall function of the human body, stagnation of blood and qi, and a large amount of acidic waste produced by the body. So far, medicine believes that cancer is not contagious.

In simple terms, infection is the transmission of a disease from one person to another through some means. Infection requires three conditions: the source of infection, the route of transmission, and the susceptible population. Lymphoma patients themselves are not the source of infection, so lymphoma is not contagious.
Cancer cells in the patient's body are a group of abnormal cells that have lost control and grow in an invasive manner. They not only destroy adjacent normal tissues and organs, but can also spread to all parts of the body through the lymphatic system and blood circulation, absorb a large amount of nutrients, grow and proliferate rapidly, and cause the patient's systemic failure and even death. Although cancer cells can spread or metastasize everywhere in the patient's body, they will not be transmitted from one person to another like bacteria and viruses. To oneself, other people's cancer cells are a kind of foreign body, and the body destroys cancer cells through its powerful immune rejection ability. Therefore, the patient's cancer cells cannot be transmitted to the family members who care for and live with them.
