Hi I've been bleeding off and on from my colon for 10 years. I'm 30 and it started when I began to diet and try to lose weight. I was taking many kinds of laxatives at the time too. Through my 20s I struggled with weight and used laxatives and bled much from my colon. It wasn't until recent that I noticed barely no blood in stool but so much blood on toilet paper. So I'm definitely concerned. Do you think this is a sign of colon cancer? I have an appointment next Friday and I'm hoping they set me up with a colonoscopy to see what's going on but should I be alarmed?
