Lymphoma affects your immune system and can cause swellings in your neck, armpit, groin, or deeper in your body.

There are different types of lymphoma. The symptoms, treatments and prognosis (outlook) depend on which type of lymphoma you have, so if you’ve just found out that you - or someone you know - has lymphoma, it’s useful to know which type it is when you’re looking for information.

The main types are Hodgkin lymphoma and non-Hodgkin lymphoma (NHL).

Doctors put non-Hodgkin lymphomas (NHLs) into two groups depending on how fast they develop: 

  • Low-grade NHLs usually develop slowly. The most common type is follicular lymphoma, but other types include marginal cell lymphoma and lymphoplasmacytic lymphoma (which is also called Waldenstrom macroglobulinaemia).
  • High-grade NHLs usually develop more quickly. The most common type of high-grade NHL is diffuse large B-cell lymphoma (DLBCL), but other types include Burkitt lymphoma and lymphoblastic lymphoma.

About 12,000 people are diagnosed with lymphoma every year in the UK. Most people with lymphoma have non-Hodgkin lymphoma.
