Acute Promyelocytic Leukemia (APL)
Acute Promyelocytic Leukemia (APL) is a type of acute leukemia that affects a specific type of white blood cell known as promyelocytes, which are found in the bone marrow. APL is a rare condition. The cause of APL is unknown. It can present as low, intermediate, or high-risk disease. The effectiveness of the treatment may depend upon the risk category (low, intermediate, or high) at diagnosis. APL is highly curable when appropriate treatment is not delayed.
