This booklet is for anyone interested in learning more about leukemia. It explains the four main types of leukemia, how leukemia is diagnosed, general methods of treatment, and how The Leukemia & Lymphoma Society can help. The progress that has been made in treating leukemia gives patients and caregivers more hope than ever before. Treatments may include drug therapy, monoclonal antibody therapy, stem cell transplantation, and for some patients, radiation therapy. More information about each type of leukemia and specific treatments is in the Society’s free booklets, including: Acute Lymphocytic Leukemia: A Guide for Patients and Families Acute Myelogenous Leukemia: A Guide for Patients and Families Chronic Lymphocytic Leukemia: A Guide for Patients and Families Chronic Myelogenous Leukemia: A Guide for Patients and Families
