types of leukemia disease
The four most common types of leukemia are acute lymphocytic leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, and chronic myeloid leukemia. Acute lymphocytic leukemia (ALL, also known as acute lymphoblastic leukemia) is the most common type of leukemia in children, but it can also affect adults. In this type of leukemia, immature lymphoid cells grow rapidly in the blood. It affects over 6,000 people per year in the U.S.
