Leukemia Screening and diagnosis
Leukemia is a form of cancer unlike any other, and one of the more dangerous. The term leukemia refers to cancers of the white blood cells (also called leukocytes or WBCs). Leukemia is cancer of your body's blood-forming tissues, including the bone marrow and lymph system. The word leukemia means "white blood" in Greek. The disease usually starts in the white blood cells. Under normal circumstances, your white blood cells are potent infection fighters. These cells normally grow and divide in an orderly, controlled way, as your body needs them. But leukemia disrupts this process. In people with leukemia, the bone marrow produces a large number of abnormal white blood cells. They look different from normal blood cells and don't function properly. Eventually, they block production of normal white blood cells, impairing the ability to fight off infection. Leukemia cells also crowd out other types of blood cells produced by the bone marrow, including red blood cells, which carry oxygen to tissues throughout the body, and platelets, which help form blood clots that control bleeding. Leukemia isn't just a children's disease, as some people think. Leukemia has four main types and many subtypes - and only some of them are common among children. Overall, this form of cancer affects about 10 times as many adults as children. Leukemia is usually fatal without successful treatment. Screening and diagnosis Doctors often find chronic leukemia in a routine blood test, before symptoms begin. If this happens, or if you or your child has symptoms that suggest leukemia, you may undergo the following diagnostic exams:
Additional tests are needed to confirm the diagnosis and to determine the type of leukemia and its extent in your body. Certain types of leukemia are classified into stages, indicating the severity of the disease. Staging helps your doctor determine a treatment plan.
