No, acute myeloid leukemia (AML) is not the most common type of childhood leukemia. Acute lymphoblastic leukemia (ALL) is the most common form of leukemia in children, accounting for about 80% of all childhood leukemia cases. AML is the second most common type of leukemia in children, accounting for about 15% of all childhood leukemia cases.
AML is most common in adults, usually occurring between the ages of 15 and 44. It can also affect children, but is much less common in this age group than ALL. When it does occur in children, it often affects younger children and has a poorer prognosis than ALL.
ALL is a cancer of the white blood cells that is characterized by an overproduction of immature white blood cells, known as lymphoblasts. It is the most common type of leukemia in children, typically affecting those under the age of 15. It is also the most treatable form of childhood leukemia, with a cure rate of over 90%.
In contrast, AML is a cancer of the white blood cells that is characterized by an overproduction of immature myeloblasts. It is much less common in children than ALL. When it does occur in children, it tends to affect younger children and has a poorer prognosis than ALL. Treatment for AML is often more intensive than for ALL, and the cure rate is lower.
Overall, acute lymphoblastic leukemia is the most common type of childhood leukemia, accounting for about 80% of all cases. Acute myeloid leukemia is the second most common type of childhood leukemia, accounting for about 15% of cases, and is more common in adults than in children.
