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.
Mantle cell lymphoma (MCL) is a 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.
