Hi Patricksgirl, In my opinion there is a difference between being proactive about prevention and worrying. It sounds like you are taking your health seriously, especially knowing that you have a family history of colorectal cancer. I do too. During my second colonoscopy they removed a pre-cancerous polyp. I plan to continue having regular colonoscopies. However, I don't think about it between colonoscopies. How often do you get a colonoscopy? Do you worry about cancer between your screening tests?
