what is the difference between follicular lymphoma and b cell lymphoma?
Follicular lymphoma (FL) is a slow-growing type of non-Hodgkin lymphoma. 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.
