How does leukemia work?
“What is leukemia? Leukemia is cancer of the blood cells. Blood cells are made by your bone marrow, which is the soft tissue in the middle of most bones. Leukemia starts with chromosome changes in cells. These changes are called mutations, and mutations change the way cells work and grow. With leukemia, the bone marrow starts making too many white blood cells, and sometimes these cells don’t work right. These cells keep growing when they are supposed to stop. They also grow faster than your other cells. Over time, these abnormal cells crowd out your normal white blood cells, red blood cells, and platelets. Your white blood cells help your body fight infection. Your red blood cells make sure all your body parts have the oxygen they need. Your platelets keep you from bleeding too much. When the leukemia cells crowd out your normal cells, your blood cannot do its job. You may bleed or bruise easily, get sick more often, and feel very tired.” There is much, much more to study at this websi
