It starts in the bone marrow.When you have leukemia, the bone marrow starts to make a lot of abnormal white blood cells, called leukemia cells.They grow faster than normal cells, and they don't stop growing when they should
.Over time, leukemia cells can crowd out the normal blood cells. This can lead to serious problems such as anemia, bleeding, and infections. Leukemia cells can also spread to the lymph nodes or other organs and cause swelling or pain.]]> 2017-04-25 06:13:09 UTC https://padlet.com/rupaleem1/zk4hgir4zkjg/wish/168013909 https://padlet.com/rupaleem1/zk4hgir4zkjg/wish/168013913 Cancer of blood cells

Leukemia affects the body by disrupting the normal balance of cells in the blood and their ability to do their jobs. Reduced levels of white blood cells, which normally defend the body from infection, can lead to higher chances of catching secondary diseases. Reduced levels of platelets, the cells that cause blood to clot, lead to more frequent bruises and nosebleeds. If the cancerous cells spread to the brain, headaches and nausea can result from tissues around the brain and spinal cord becoming irritated and inflamed. Finally, painful bones can result from the cancerous cells spreading into the bone marrow.]]> 2017-04-25 06:13:13 UTC https://padlet.com/rupaleem1/zk4hgir4zkjg/wish/168013913 https://padlet.com/rupaleem1/zk4hgir4zkjg/wish/168013934 There are four main blood groups (types of blood): A, B, AB and O.
