About this study

This study is being done to find biologic abnormalities in the lymphocyte cells of patients with CLL (Chronic Lymphocytic Leukemia). In order to validate these tests, cells from patients with CLL will be studied when the tests are ready in the laboratory. This study is also being done to learn more about the environmental and genetic factors that might be responsible for CLL. Finding such factors would help us understand the causes and possible prevention of this cancer.
