Sleeping It Off is one of 27 oil paintings by British artist Susan Macfarlane that seek to illustrate what it is like to live with childhood leukaemia. The paintings reveal a complex environment of laboratory testing and diagnosis, blood transfusion, the children's ward, radiotherapy, chemotherapy, bone marrow transplant and the follow-up. Living With Leukaemia, painting of childhood leukaemia, is on

display in the Barbican Centre's foyer gallery, Silk Street, London, until 8 March.
