4- Frequent cases of infections and fever
If lately you have been experiencing fever and a number of infections, this can be a sign of leukemia. Leukemia is a type of cancer that affects the blood cells and causes the body to produce weak and abnormal white blood cells, weakening the body’s immune system in general. Be cautious and pay attention to any symptoms similar to the ones likely to be experienced in flu cases. The symptoms can include fever or achiness that persists for a very long time.
