Relapse in Chronic Lymphocytic Leukaemia (CLL) A Guide for Patients Introduction A relapse is the return of leukaemia after treatment. Specifically, this booklet is about a relapse in chronic lymphocytic leukaemia (CLL). The booklet was written by our Patient Information Writer, Isabelle Leach, and peer reviewed by Helen Knight, CLL Clinical Nurse Specialist at the Centre for Clinical Haematology in Nottingham University Hospitals. We are also grateful to our patient reviewer, Amanda Salter, for their contribution.

In chronic lymphocytic leukaemia lymphatic vessels, which run (CLL), the lymphocytes in the adjacent to the small blood bone marrow start multiplying vessels in the body, drain lymph excessively leading to large fluid from all over the body to numbers of abnormal, immature clear excess fluid and act as cells called blasts, which prevent a blood filter helping to fight the bone marrow from producing infection with the help of the enough healthy blood cells of all B-cells and T-cells. types.
