Welcome to the Hairy Cell Leukemia (HCL) Consortium patient community. This space is where patients, and their families and friends, can learn all about HCL from its history, to symptoms and treatment, to what it means to live with the disease. We hope that individuals will use this community as their primary source of knowledge on HCL as well as to reach out to the leading clinicians and researchers around the world to ensure access to the latest treatments and care available.
