Lymphoma Education | Hodgkin & Non-Hodgkin Types

Lymphoma


Lymphoma is a blood cancer that originates from abnormal lymphocytes, a type of white blood cell that help defend the body against foreign invaders like bacteria and viruses.1

There are two main types — Hodgkin lymphoma and non-Hodgkin lymphoma. Hodgkin lymphoma and non-Hodgkin lymphoma can occur in children, teens and adults of any age. 2

Hodgkin Lymphoma


Hodgkin lymphoma, when active, often travels from one group of lymph nodes to the next in a predictable path. 3 The diagnosis process includes a series of tests to decipher the disease stage which can range from Stage I to Stage IV. In Stage I, only one lymph node region or single organ is affected. As the stages progress, more lymph node regions are affected, and in Stage IV, multiple organs and lymph node regions above and below the diaphragm are affected. 4 Hodgkin lymphoma treatment generally consists of combination chemotherapy plus/minus radiotherapy. After initial treatment, the majority of Hodgkin lymphoma patients will be considered cured, as many will achieve not only complete remission, but a long-term remission. 5

Non-Hodgkin Lymphoma


More than 60 non-Hodgkin lymphoma subtypes have been identified and assigned names by the World Health Organization (WHO), characterized by appearance, anatomical localization and cell composition. 6 These subtypes of non-Hodgkin lymphomas are divided into two major groups: T-cell lymphomas, which develop from abnormal T-lymphocytes, or B-cell lymphomas, which develop from abnormal B-lymphocytes. There are many different forms of T-cell lymphomas, some of which are extremely rare. T-cell lymphomas can be aggressive (fast-growing) or indolent (slow-growing). 7 There is no one-size-fits-all approach to treating non-Hodgkin lymphoma. Subtypes can vary so much that they present as a practically different disease altogether, so treatment options also vary greatly. 8
