Lymphoma is cancer that begins in infection-fighting cells of the immune system, called lymphocytes. These cells are in the lymph nodes, spleen, thymus, bone marrow, and other parts of the body. When you have lymphoma, lymphocytes change and grow out of control.
There are two main types of lymphoma:
- Non-Hodgkin: Most people with lymphoma have this type.
Non-Hodgkin and Hodgkin lymphoma involve different types of lymphocyte cells. Every type of lymphoma grows at a different rate and responds differently to treatment.
Lymphoma is very treatable, and the outlook can vary depending on the type of lymphoma and its stage.

The 5-year survival rate for all people with Hodgkin lymphoma is 87%. The 5-year survival rate for stage I is 92%. The 5-year survival rate for stage II Hodgkin lymphoma is 93%. Approximately 40% of people are diagnosed with this stage. For stage III, the 5-year survival rate is 83% and for stage IV, it is almost 73%.
