What should I know about
follicular lymphoma?

  • Follicular lymphoma (FL) is a type of blood cancer.
  • FL occurs when certain white blood cells, called B lymphocytes, grow and multiply uncontrollably.
  • These cancerous lymphocytes can travel to different parts of the body, such as the lymph nodes, spleen, bone marrow, and other organs.
  • Although FL typically grows and spreads slowly, most people will eventually have progressive FL that requires multiple treatments.
FL occurs when certain white blood cells,
called B cells, grow and multiply uncontrollably.

What is “relapsed or refractory” FL?

You may hear your healthcare team refer to your cancer as being “relapsed” or “refractory.” Relapsed means that your cancer came back after being treated. Refractory means that your cancer does not respond to treatment and cancer cells continue to grow.

Your healthcare team may decide to try a new treatment if you have relapsed or refractory FL. Depending on your unique situation, your doctor may recommend different treatment options.
