There are two primary categories of lymphomas: Hodgkin lymphoma and non-Hodgkin lymphoma (NHL). Beyond that, there are many different subtypes, especially subtypes of non-Hodgkin lymphoma.
Some lymphomas arise from B-lymphocytes, while others arise from T-lymphocytes. Lymphomas are also described by their growth rate, with rapidly growing lymphomas referred to as “aggressive” and slow-growing lymphomas referred to as “indolent.”
When caught early, most lymphomas can be successfully treated. There is some difference in the treatments and their likely outcome (prognosis) based on the type of non-Hodgkin lymphoma. A medical oncologist, who treats cancer, is also trained in blood diseases, including lymphoma. The medical oncologist/hematologist will be the lead for your treatment planning.
Non-Hodgkin lymphoma (NHL) is the most common type of lymphoma. Generally, it develops in the lymph nodes and lymphatic tissue found in organs such as the stomach, intestines or skin. Sometimes, however, NHL involves bone marrow and blood.
There are several different subtypes of non-Hodgkin lymphoma, which are categorized by the characteristics of the lymphoma cells, including their appearance, the presence of proteins on the surface of the cells, their genetic features, and how fast (or slow) they progress.
