Risk Factors
About one out of 45 to 50 persons will develop lymphoma sometime during their lifespan. Non-Hodgkin lymphoma is currently, the eighth most common lymphoma in both men and women. Although the exact causes for most lymphomas are not known, doctors recognize certain "risk factors" for development of this cancer. A risk factor is a characteristic, behavior, or condition that raises the possibility of developing a disease. Here are some factors known to increase the risk of developing non-Hodgkin lymphoma:
Age
Non-Hodgkin lymphoma occurs more often in people over the age of 60, although some forms occur more often in younger people.
Gender
Men are generally at higher risk for non-Hodgkin lymphoma than women, but some types of the disease are more prevalent in women.
Race
White people are at a higher risk for developing non-Hodgkin lymphoma than African-Americans and Asian-Americans.
Viruses/Bacteria
Infection with the Epstein-Barr virus (EBV), Helicobacter pylori bacteria, and hepatitis C virus (HCV) may increase the risk for development of non-Hodgkin lymphoma.
Immune Deficiency
Having a weakened immune system due to the HIV virus, an organ transplant, or certain inherited genetic traits may increase the risk for non-Hodgkin lymphoma.
Autoimmune Diseases
Autoimmune diseases like lupus and rheumatoid arthritis may put one at higher risk for non-Hodgkin lymphoma.
Diet/Obesity
Being overweight (obese) or eating a diet high in fat and red meats may increase the risk for development of non-Hodgkin lymphoma.
Environmental/Occupational Exposure
Exposure to carcinogenic toxins such as pesticides and insecticides may increase the risk for developing non-Hodgkin lymphoma. Certain medications, particularly medications that suppress the immune system may also increase the risk for development of lymphomas.
