The lymph nodes make and store infection-fighting cells. Because lymph tissue is found in many parts of the body, non-Hodgkin's lymphoma can start in almost any part of the body. The cancer cells in Hodgkin's disease look a certain way under a microscope. Non-Hodgkin's lymphoma can also occur in children and is treated differently. There are many types of non-Hodgkin's lymphomas.
Some types spread more quickly than others.
The type is determined by how the cancer cells look under a microscope. This determination is called the histology. For questions or comments about this site, please contact the webmaster.
