The Leukemia & Lymphoma Society (LLS) is dedicated to finding a cure for leukemia, lymphoma, myeloma, and Hodgkin's disease. It is the world's largest voluntary health organization dedicated to funding blood cancer research. It also advocates for legislation and insurance coverage at both state and national government levels, and provides education programs and publications for health professionals and support for patients and their families. The LLS has chapters throughout the US and Canada. Nearly all of the group's revenue comes from contributions made in response to its fund-raising campaigns. Since its establishment in 1949, LLS has awarded more than $875 million in research funding.
