Lymphoma is best seen as “cancer of the immune system”. There are over 66 different types of lymphomas. The reason for that high number is that there are many different cell types that make up the immune system that can give rise to cancerous lymphoma cells. The two main categories of lymphomas are Hodgkin lymphomas (HL) and the non-Hodgkin lymphomas (NHL). About 90% of lymphomas are the NHL type while about 10% are Hodgkin lymphomas. NHL has many different subtypes which are either indolent (slow growing) or aggressive (fast growing).
Lymphoma generally develops in the lymph nodes and lymphatic tissues. It can involve bone marrow, blood, and any organ system.
Knowing the exact types of lymphoma is important because it affects the curability, prognosis and treatment options. It is therefore highly recommended to consult with a lymphoma expert team to make the right diagnosis and develop the right treatment plan.
