Colorectal or colon cancer often happens when the cells which line the rectum or colon grow out of control and become abnormal. As this condition develops, it would bleed into your digestive tract and cause bloody or dark stool. Over time, your blood loss could accumulate and result in anemia or low counts of red blood cells. While this is a severe health issue, it could be treated with early detection. Thus, it is advisable to visit your doctor as soon as you see blood in your stool. [9]
