Acute Myeloid Leukemia (AML) is a type of blood cancer. It forms when the body produces abnormal white blood cells (which are normally infection fighters). These cells then interfere with the body's ability to produce normal blood cells. AML is largely diagnosed in older adults (over age 65). Symptoms may include fatigue, easy bruising, and fever. Abnormal blood test findings may be the first sign that AML is present; a bone marrow biopsy can confirm the diagnosis including details around subtype. As with many forms of cancer, it is not exactly clear what the cause of AML is, but there are several risk factors that point to an increased risk: genetics, environmental exposure (especially chemicals, such as benzene), and previous cancer treatments (specifically, chemotherapy and radiation). AML can be challenging because symptoms may be downplayed or confused for other conditions, yet it tends to grow aggressively. At diagnosis there may be imaging tests to see if the leukemia has spread to other areas.
