As of 2015, there are only four known types of lymphoma, reports the American Cancer Society: Hodgkin disease, non-Hodgkin lymphoma, Waldenstrom macroglobulinemia and lymphoma of the skin. Lymphoma is a cancer of the lymphocytes, immune system cells located in the lymph nodes, according to WebMD.
Common symptoms of lymphoma include painless swelling of the lymph nodes, weight loss, headache, night sweats and fatigue. Some patients may also experience itching, loss of appetite and trouble breathing, reports the Lymphoma Coalition. Lymphoma is most likely to affect men, people over age 60 and people with a compromised immune system; however, the cancer can appear in people who have been exposed to benzene, pesticides, herbicides and radiation therapy, notes WebMD.
It is important for people with lymphoma to get early treatment for the disease. The majority of patients visit a doctor within one year of the onset of symptoms; however, lymphoma symptoms often resemble the symptoms of other minor illness, according to the Lymphoma Coalition. As of 2015, there is no blood test or screening test to diagnose lymphoma.
The condition is highly treatable, state WebMD. With treatment, doctors can cure certain lymphomas. There is a different course of treatment for each type of lymphoma.
