Which type of leukemia constitutes 80% of acute leukemia in adults?

Acute Myeloid Leukemia (AML) constitutes about 80% of acute leukemia cases in adults, making it the most common type among this population. AML originates from the myeloid cell line, which is part of the hematopoietic system that produces blood cells. The disease is characterized by the rapid proliferation of immature myeloid cells in the bone marrow, which disrupts normal hematopoiesis and leads to a variety of symptoms such as fatigue, increased susceptibility to infections, and bleeding complications due to cytopenias.

In adults, the presentation of AML often occurs more frequently than other types of acute leukemia, such as Acute Lymphoblastic Leukemia (ALL), which is more common in children. Chronic forms of leukemia, such as Chronic Lymphocytic Leukemia (CLL) and Chronic Myeloid Leukemia (CML), also differ from acute leukemias, emphasizing the quick progression and the urgent clinical management typically seen with AML. Understanding the prevalence of AML among adults is crucial for appropriate diagnosis, treatment planning, and follow-up care in clinical practice.
