Hairy cell leukaemia

Hairy cell leukaemia (HCL) is a rare type of slow-growing blood cancer. It affects white blood cells called B lymphocytes. It’s called hairy cell leukaemia because, under a microscope, the cancer cells look hairy.

This booklet covers what HCL is, how it may affect you, diagnosis, and treatment options. We also include practical information about living with HCL.
