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

Very rarely. The. whole point of most cancers, & many other diseases (such as arterial disease which ~50% of population has started by later childhood), is that there are no symptoms, the whole point of focusing on other indicators such as colonoscopies for colon cancer, BEFORE symptomatic.

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. Read more...
