Leukemia is classified as acute or chronic depending on how fast symptoms appear. Symptoms for acute leukemia appear faster and may prompt a visit to the doctor. Chronic leukemia is a much slower process. Some people may notice symptoms months or years after leukemia first appears, while others may have no symptoms at all. In people with no symptoms, leukemia may be found incidentally during a routine blood test.
If you experience any symptoms, do not assume it is due to cancer. Many symptoms can be caused by other, less serious conditions. However, it is still important to discuss them with your doctor. Early detection and treatment improve outcomes for both cancer and other health conditions.
Symptoms will depend on the type of blood cells that are affected.
A drop in the number of normal white blood cells makes it harder for the body to fight infection and may lead to: Persistent fever that is not specific to another conditionFlu-like symptomsNight sweatsMinor cuts that heal slowly—the area around the cut may become red and swollen
A drop in the number of normal red blood cells is called anemia, which decreases the amount of oxygen reaching the body's tissues. Symptoms of anemia may include: Weakness and fatiguePale skinHeadache
A drop in the number of normal platelet cells makes it harder for blood to clot properly. Without clotting, even small injuries can lead to severe bleeding. Symptoms may include: Bleeding or bruising easilyNosebleedsBleeding gumsTiny red spots under the skinHeavy menstruation
Later stages of leukemia may cause: Swollen, tender lymph nodes Swelling of the liver or spleenPuffy gumsRashDecreased appetite and unintended weight lossBone or joint painDifficulty breathingSwelling of the testiclesNervous system problems, including:
HeadachesNauseaLoss of muscle controlSeizures
