“Blood cancer endangers an essential life force: your blood cells. These cells give you energy, help you fight infection, and keep you from bleeding too much. When faulty DNA causes your blood cells to become cancerous, the cancer puts all these important functions at risk. Fortunately, there are many effective and safe ways to treat blood cancer.

Blood cancer affects how your body produces all types of blood cells and how well those cells work. Most blood cancers start in your bone marrow; this is where most of your cells are produced and let into the bloodstream and mature into adult size cells. This is the soft, sponge-like material in the center of your bones. Your bone marrow makes stem cells that mature and become one of the following:  Red blood cells, which carry oxygen throughout your body, White blood cells, which fight infection, Platelets, which control bleeding.

Blood cancer happens when something disrupts how your body makes blood cells. The cancer cells can’t do the jobs normal blood cells do. Instead, the abnormal blood cells multiply unchecked and overwhelm the normal ones.

Like any type of cancer, blood cancer is a serious diagnosis. But the good news is that more and more people are surviving blood cancer.”
