There is a 24 percent chance of surviving five years among those diagnosed with acute myeloid leukemia, and reaching the five-year mark is a good indicator of long-term survival, as WebMD explains. The average age of a patient with AML is 67, according to the American Cancer Society.
AML is a blood cancer that originates in the bone marrow. With AML, a patient's bone marrow cells do not develop as they should, and the immature cells and blast cells compound and spread to other body parts, such as the lymph nodes, liver, spleen, testicles, brain and spinal cord, as WebMD explains.
As of 2015, there are over 20,000 reported cases of AML in the United States, mainly among adults. It is rare to develop the disease prior to reaching the age of 45. Men are diagnosed with AML more often than women, but the risk of the developing it is less than 1 percent among both men and women, according to the American Cancer Society.
A better prognosis is achieved with a better body response to treatment. A patient under 60 years of age without a history of blood disorders or cancer and without gene mutations or chromosome changes has the best prognosis. Although the exact cause of AML is unknown, a patient can reduce the risk of developing the disease by not smoking and limiting chemical exposure, as WebMD advises.
