It is best to read this information with our general information about non-Hodgkin lymphoma (NHL). If you have any more questions, you can ask your doctor or nurse at the hospital where you are having treatment.
Nodal marginal zone B-cell lymphoma (NMZL) is a slow-growing type of NHL. It develops when B-cells (also called B-lymphocytes) become abnormal. B-cells are white blood cells that fight infection.
The abnormal B-cells (lymphoma cells) usually build up in lymph nodes, but they can affect other parts of the body.
Nodal means the lymphoma started in the lymph nodes. The marginal zone is an area of the lymph nodes. This is where the abnormal B-cells are found in NMZL.
