I've been looking into some symptoms I've been experiencing for many years, and they are pointing to a genetic condition called Ehlers-Danlos syndrome. Long story short, there's a very interesting presentation here: https://www.ehlers-danlos.com/2014-phys ... ollins.pdf
There are lots of GI implications for people with the disease. While it doesn't mention colorectal cancer, there are some possible links related to increased gut permeability and more trauma to the gut as a result. If you have symptoms mentioned in the presentation, it doesn't hurt to get a genetic test to see if it's an issue in your situation. I'm getting tested soon.
The disease affects the body's formation of collagen. There are several subtypes. They can include joint hypermobility, bruising, fragile skin, gum disease, food allergies, gluten intolerance, GERD, IBD, Crohn's, etc. Worth a discussion with your doctor if you have any of these. Bowel perforation during colonoscopy is specifically mentioned.
