Overview

There is no single definitive description of the non-Hodgkin’s lymphomas because the term NHL encompasses a collection of diseases. How they relate to other lymphomas and leukemias–and if they really are different entities–is still under debate.

There are many theories about potential causes of NHL, but studies are not conclusive. There is much that is not fully understood. There are, however, certain general medical descriptions of NHL that can be made, as well as comparisons to other lymphomas and other cancers. The current state of knowledge about causes, types of NHL, and staging can be described.
