Is metastatic lymphoma contagious?

According to years of medical research at home and abroad, the conclusion is that cancer is not contagious. So lymphoma is not contagious either. 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 lymphatic channels 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 will destroy the cancer cells through its powerful immune rejection ability. Therefore, other people's cancer cells cannot survive in one's body.

Since cancer is not contagious, can it be inherited? We say that infection and inheritance are two completely different medical concepts. The former is an infectious disease caused by bacteria or viruses, such as tuberculosis, hepatitis, etc., while the latter is due to blood ties, causing multiple people in the family to suffer from the same disease. If one of the parents suffers from a certain type of cancer, their children are more likely to suffer from the same type of cancer, and have a clear family history of tumors.

The survey results show that the incidence of cancer patients is higher in blood relatives than in non-blood relatives, higher in close relatives than in distant relatives, and no significant difference between paternal and maternal relatives, indicating that the incidence of cancer is related to genetic factors. It has been confirmed that several tumors such as retinoblastoma, colon polyposis syndrome, Wilms tumor, and neuroblastoma have a significant genetic tendency. Other cancers related to genetics include: esophageal cancer, gastric cancer, breast cancer, kidney cancer, colon cancer, and nasopharyngeal cancer. For people with a family history of cancer, regular examinations and the arrangement of key protective measures are an effective prevention method, which has important clinical significance for the early detection, early diagnosis, and early treatment of tumors.
