What is lymphoma?

Lymphoma is a cancer that develops in the part of the body that protects us from disease and infection, called the lymphatic system. It can happen in children and adults. Lymphoma begins when an abnormal lymphocyte, a type of white blood cell found in the lymphatic system, reproduces uncontrollably. In some cases, masses may form in the lymph nodes, liver, spleen, and/or other parts of the body.

Why the type of lymphoma matters

There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. The treatment for lymphoma varies according to the type or subtype and whether the cancer progresses quickly or slowly. You may find that learning about your diagnosis once you know the type and subtype of lymphoma involved will help you better understand the disease and its treatment.
