Colon cancer signs for women and men should not be ignored. According to the Centers for Disease Control and Prevention, almost 140,000 people are diagnosed with colorectal cancer every year in America. Rectal bleeding is the most obvious colon cancer symptom, but there are other, more subtle signs, like learning you're anemic. It may be the first sign that you're bleeding internally. Other signs are you can't catch your breath, you feel bloated or crampy and you have severe constipation.
