There are many types of non-Hodgkin lymphoma (NHL). Your doctor needs to know which type you have so that they can give you the best treatment.

What are B-Cell and T-cell lymphomas?

Lymphomas develop from abnormal lymphocytes. There are two main types of lymphocyte: B-cell lymphocytes and T-cell lymphocytes.

If a lymphoma developed from abnormal B-cell lymphocytes, it is called a B-cell lymphoma. If it developed from abnormal T-cell lymphocytes, it is called a T-cell lymphoma.
