What are some pre-cancerous signs of colorectal cancer?

Colonic polyps. Nearly all colon cancers arise in colon polyps. Unfortunately, colonic polyps are generally asymptomatic and require colonscopy of barium enema for detection. Newer imaging studies may make the detection easier. Patients with inflammatory bowel disease have higher incidence of colon cancer. A family history of colon cancer is an other "sign".
ColOn cancer symptom. 75% polyps and 50% of colon cancers cause no early symptoms thus the importance of screening. If symptoms are present, then blood in the stool and change in bowel habits lead the list.

I have chronic dry, hard stool and go 4-6d/wk that started 6 mo ago. How often is this the only sign of colorectal cancer?

Not likely. Now, if you have a change in stool diameter, or color, such as black or red stained stools, that would be suspicious. Hard, dry stool is often a sign of lack of water and/or dietary issues. I suggest lots of water, a balanced diet with fiber, vegetables, and fruits. Limit alcohol intake. Talk to your doctor or health provider. Don't take more fibre supplements than are recommended. Good luck.
Cancer unlikely. First, you are very young. Colon cancer almost never occurs at this age. Second, this would not be a typical symptom at any age. I encourage a diet high in fruits and vegetables and that you drink plenty of fluids. If the problem persists, see your doctor.
