Follicular Lymphoma Fund

Follicular lymphoma (FL) is a form of non-Hodgkin lymphoma that affects cells called B lymphocytes. The most common symptom is painless swelling of lymph nodes. Other symptoms may include fatigue, unexplained weight loss, night sweats, and frequent infections. FL usually progresses slowly over years but can occasionally transform into a more aggressive lymphoma.

Close to 14,000 new cases are expected to be diagnosed each year in the US. The disease primarily affects older adults and is more common in Caucasians, with non-Hispanic whites having the highest incidence rate of 4.1 per 100,000, compared to 2.4 for non-Hispanic blacks and 1.7 for Asian/Pacific Islanders.
