Transcript of Leukemia
Common Leukemia symptoms:
Fever or chills
Swollen lymph nodes
persistent fatigue, weakness
enlarged liver or spleen
easy bleeding and bruising
small red spots on skin (petechiae)
The exact cause of Leukemia is unknown, but it is said to be a combination of genetic and environmental factors. Leukemia is formed by mutations that occur in cells DNA causing them to grow abnormally and lose functions in white blood cells.
Most types of Leukemia is not preventable, yet some types can be prevented by:
avoiding high doses of radiation
exposure to the chemical benzene
smoking and other tobacco use
-kills Leukemia cells in the blood and bone marrow to induce remission. Includes Chemotherapy and Corticosteroids.
-kills Leukemia cells that may be present that don't show up in tests. Includes Chemotherapy and possibly a stem-cell transplant.
-also prevents Leukemia cells from growing. Includes lower doses of Chemotherapy. This stage is often continued for up to 3 years.
Because many types of leukemia don't show symptoms early in the disease, leukemia may be diagnosed accidentally during a physical exam or as a result of routine blood testing. A blood test showing an abnormal white blood cell count might suggest the diagnosis. To confirm the Leukemia, a needle biopsy and aspiration of bone marrow from a pelvic bone will need to be done to test for leukemic cells, DNA markers, and chromosome changes in the bone marrow.
Acute lymphocytic leukemia
- the type of leukemia that most commonly affects children, most often between the ages of 2 and 3 years. ALL accounts for about 73 percent of leukemia cases each year in the US.
Acute myelogenous leukemia
- the most common form of leukemia in adults. This is the second most common type in children and usually occurs by the age of 2.
