Funding the LLS Mission

Big Climb helps The Leukemia & Lymphoma Society (LLS) support cutting edge research projects in the most promising areas of cancer research. The impact of LLS-supported research goes beyond blood cancers. Approximately 40 percent of new cancer therapies approved by the FDA since 2000 were first approved for a blood cancer – which have led to breakthrough treatments for other cancers and serious diseases.
