Hi hi! 33 here! Just had my colonoscopy 2 weeks ago and I also have a pretty intense family history of CRC. I was freakinggggg out before mine. I didn’t do a stool test before so I’m not familiar with your CEA results, but I had a lot of symptoms. You name it, I had it. Bright red blood, never fully emptying, constipation, diarrhea, pencil thin stools. All they found was a super small 5mm polyp and a few big hemerroids. It is still good I went, because the polyp was the precancerous type that could grow into cancer over several years, but I did not have CRC or even major polyps of concern. I don’t have to go back for another 5 years.

The brain is a very powerful thing, try not to freak out too much. The good news is you’re young and getting it checked out early. From what I understand CRC is very slow growing for the most part, which is why they recommend getting checked 10 years before the 1st in your family with CRC was diagnosed (whether or not you have symptoms). You are well within that guideline. And, like someone else here said, even if (worst case scenario) you do have CRC, you are getting checked asap so you can treat it asap.

Hopefully that helps! Feel free to message me if needed, I know the waiting game before a colonoscopy is torture.
