There are a few types of Non-Hodgkin’s Lymphoma but about 90% of all cases are B-cell lymphomas. Apart from the B-cell lymphoma there are also T-cell and NK cell lymphoma as well as some lymphoproliferative disorders associated with immunodeficiency.
Non-Hodgkin’s Lymphoma is sometimes known as indolent (also: low-grade) if it grows slowly, or aggressive (also: high-grade) is it grows fast. Non-Hodgkin’s Lymphoma is usually treated by oncologists and hematologists.
As with Hodgkin’s Lymphoma there are certain clearly observable stages of development of Non-Hodgkin’s Lymphoma. First lymphoma can be found in only one lymph node region. Then, the lymphoma spreads to one, or two more lymph node regions close to the first one. After that, the lymphoma is in a few lymph node regions in the abdomen, nech and chest. Finally, the lymphoma is quite widespread and can be found also in internal organs and even bones.
Among the diseases generally referred to as Slow-growing B-cell or T-Cell Non-Hodgkin Lymphoma there are:
Small cell lymphocytic lymphoma
Cutaneous T-cell lymphoma
Among the diseases generally referred to as Fast-growing B-cell or T-cell Non-Hodgkin Lymphoma there are:
Diffuse large B-cell lymphoma
Mantle cell lymphoma
Acute adult T-cell lymphoma
