Leukemia is cancer of the blood and triggers the body to produce abnormal white blood cells, sapping the body’s infection-fighting abilities by weakening the immune system. Pay attention to flu-like symptoms, like achiness or fever, which don’t go away. You should also pay attention to these early throat cancer symptoms.

But if you start to notice bruises popping up all the time, especially in strange places like your hands or fingers, it should raise an alarm.
