Leukemia
Leukemia is the most common type of cancer kids get, but it is still very rare. Leukemia involves the blood and blood-forming organs, such as the bone marrow.___1___
A kid with leukemia produces lots of abnormal white blood cells in the bone marrow. Usually, white blood cells fight infection, but the white blood cells in a person with leukemia don’t work the way they’re supposed to. ___2___The abnormal white blood cells multiply out of control1, filling the bone marrow and making it hard for enough normal, infection-fighting white blood cells to form. Other blood cells — such as red blood cells (that carry oxygen in the blood to the body’s tissues) and platelets (that allow blood to clot) — are also crowded out2 by the white blood cells of leukemia. These cancer cells may also move to other parts of the body, including the bloodstream, where they continue to multiply and build up3.
Although leukemia can make kids sick, most of the time it is treatable, and kids get better. Almost all leukemia patients are treated with chemotherapy, which means using anti-cancer drugs.
___3___Chemotherapy quickly goes to work, traveling through the blood to the bone marrow. There, the drugs can attack the cancer cells. After several weeks of chemotherapy, many kids begin to feel better.
Some children with leukemia will also have to have radiation therapy, too. ___4___
If the cancer isn’t getting better from using the usual amounts of chemotherapy and radiation, then kid with leukemia will probably need more treatment —with higher doses of chemotherapy and radiation to finally kill the cancer cells. But this heavy-duty treatment will also harm the normal cells in the kid’s bone marrow too, and the bone marrow will no longer be able to produce normal blood cells. So, doctors will then give a kid — or anyone else with bone marrow that is no longer working — normal bone marrow tissue from someone else who is healthy. ___5___
