OP's situation is different from mine because OP had a colonoscopy already before 45.
But since you mention it: I don't know how reliable Cologuard is. I did one at 45 because I was at no particular risk for colon cancer. That's supposed to cover you for three years. So at 48, I did a colonoscopy — which found a large cancerous polyp of about 4 cm. The doctor removed it, a CT scan was clear, a genetic test didn't indicate any unusual susceptibility to cancer, and a subsequent follow-up colonoscopy a few months later found nothing. I go back in about a year, and if that's also clear, I can do every three years. But still, I can't help thinking that I should have just gotten the colonoscopy at 45; is it possible there was no large cancer then (and that's why the Cologuard didn't find anything) and then it suddenly grew? Sort of seems like I missed the chance to catch it even sooner than I did.
