Acute myeloid leukemia (AML) is a type of cancer that affects the blood and bone marrow. It occurs when the body produces an excessive number of immature white blood cells, known as myeloid cells, which do not function properly. This leads to a decrease in healthy blood cells, causing symptoms like fatigue, frequent infections, and easy bruising. AML can develop quickly and requires prompt treatment, often involving chemotherapy or stem cell transplants. Risk factors include age, exposure to certain chemicals, and previous cancer treatments. Early diagnosis and intervention are crucial for improving outcomes in patients with AML.
