The colon is the largest part of the large intestine that is connected to the anus through the rectum. Colorectal (colon) cancer is a health condition where the cells in the colon or rectum grow uncontrollably. Colon cancer starts as polyp growths that are removable in the early stages. However, without proper diagnoses, the symptoms of this disease may often be misidentified and left untreated. So here are four early signs of colorectal cancer: Anemia Anemia is a deficiency of red blood cells that can cause tiredness, weakness, and shortness of breath. Anemia can be brought on by gastrointestinal complications, heavy menstruation, or trauma/surgery. However, someone who loses blood because of colon cancer is also susceptible to developing this condition. Blood in stool People with colon cancer may notice blood in their stools or rectal bleeding as an early sign of the disease. The stools may also appear black or dark, indicating dried blood. The intensity of the symptom will differ based on how far colorectal cancer has progressed. Fatigue In most instances, one mistakes fatigue as a symptom of being tired. But if one’s energy levels are low even after adequate rest, it might be a sign of colorectal cancer.
