This booklet provides information about the more common types of non-Hodgkin lymphoma for patients and their families, including diagnosis, staging and treatment. A brief description of normal blood, marrow and the lymphatic system is provided for background. Most sections of this booklet provide information that applies to all NHL subtypes.
A physical examination, imaging tests (also called "diagnostic radiology"), tissue biopsies and blood tests are used to determine the extent of the patient's NHL. This process is called "staging," and the information is used to determine appropriate treatments such as whether radiation therapy should be part of the patient?s treatment regimen.
