There are no specific guidelines to follow to prevent Non-Hodgkin's and Hodgkin's lymphoma. In most cases, the cause is not known. However, an association has been shown between the development of lymphoma and immunodeficiency disorders either inherited at birth, developed in utero, acquired or developed through the use of immunosuppressive drugs. Some examples include Acquired Immunodeficiency Syndrome (AIDS); inherited diseases affecting the immune system; and taking drugs after organ transplants to help prevent rejection.

Some chemicals have been linked to the development of lymphoma. These include some pesticides, solvents, and dyes. Also, certain viruses such as the Epstein-Barr virus, Human Herpes 8 virus and HTLV-1 have been implicated in the development of some lymphomas. That is not to say that infection by one of these viruses means you will develop lymphoma. Rather, some epidemiological evidence points to an association between these viruses and lymphoma. But, only a small percentage of people infected with any of these viruses will go on to develop lymphoma.

Even though there are some known risk factors for lymphoma, the majority of cases have unknown causes and the patients have no known risk factors.
