People who have anemia experience shortness of breath, constant fatigue, general weakness and pale coloration of the skin. A simple blood test is enough to determine whether you are suffering from anemia or not.
Since rectal bleeding and/or bloody stools is present in most cases of colon cancer, healthy red blood cells are lost from the body. This is why anemia is a good indicator of whether something is wrong with the colon.
