B-Cell Lymphomas
About 85% of the non-Hodgkin lymphomas diagnosed in the U.S. are B-cell lymphomas, which means they originate from the B-cell. Diffuse large B-cell lymphoma (DLBCL) is the most common one followed by its subtype primary mediastinal B-cell lymphoma, a fast-growing but usually easy to treat lymphoma. The rarer intravascular large B-cell lymphoma falls next on the list.
