What is non-Hodgkin lymphoma?

Lymphoma is cancer that begins in the lymph system in white blood cells called lymphocytes. When these cells become abnormal, they don't protect the body from infection or disease. They also grow without control and may form lumps of tissue called tumors.

Non-Hodgkin lymphoma (NHL) can start almost anywhere in the body. It may start in a single lymph node, a group of lymph nodes, or an organ such as the spleen. Or it can spread to almost any part of the body, including the liver and bone marrow.

There are many types of NHL. Sometimes they are grouped as:

  • Slow-growing lymphomas, which spread slowly and cause few symptoms. These may also be called indolent or low-grade lymphomas.
  • Fast-growing lymphomas, which spread quickly and cause severe symptoms. These may also be called aggressive lymphomas and may be classified as intermediate-grade or high-grade.

Treatment can cure some people and may allow others to live for years. How long you live depends on the type of NHL you have and the stage of your disease (how far it has progressed).
