This National Cancer Institute (NCI) booklet [NIH Publication No. 07-1567] is about non-Hodgkin lymphoma,* a cancer that starts in the immune system. Non-Hodgkin lymphoma is also called NHL. Each year, more than 63,000 Americans learn they have non-Hodgkin lymphoma.

This booklet tells about diagnosis, treatment, and supportive care. Learning about the medical care for people with lymphoma can help you take an active part in making choices about your own care.

This booklet has lists of questions to ask your doctor. Many people find it helpful to take a list of questions to a doctor visit. To help remember what your doctor says, you can take notes or ask whether you may use a tape recorder. You may also want to have a family member or friend go with you when you talk with the doctor - to take part in the discussion, to take notes, or just to listen.
