Diagnosis Cancer

Chronic Myelogenous Leukemia

Chronic myelogenous leukemia is generally suspected when tests reveal an elevated white blood cell count with immature "myeloid" cells in the blood.

The diagnosis is then confirmed by the presence of the Philadelphia chromosome, either by chromosome analysis, called cytogenetics, or by molecular testing for the abnormal BCR/ABL gene. A bone marrow biopsy helps determine whether the CML is in the chronic or advanced stage.
