Welcome to the Hairy Cell Leukemia (HCL) Consortium web portal. This site brings together patients, providers and the research community in order to advance our understanding of HCL, and to enable patients, and those who care for them, greater access to state-of-the-art clinical expertise and therapies. We encourage you to use the site to increase your knowledge of HCL and interact with some of the leading experts on the disease. In addition, we hope you will tell your friends, family members and colleagues to visit the site and provide feedback on the content as we embark on a collaborative effort to improve the lives of those living with HCL.
