I agree with roadrunner & utalgal7 especially at your age. Very rare at your age, unless colon cancer runs in your family. Is there a family member you could ask about prior relatives with a cancer history?
Around here, Arizona, 3 months just to see the GI doc especially for that 1st visit is not uncommon. Unless you get some type of doctor to doctor referral.
IF, and that is a big IF, you do have this cancer, it is probably a very slow growing cancer at this stage. They figured I had my cancer for about 10 yrs before it was diagnosed. That was 16+ years ago & I am very much alive & kicking today. What this means, you should have been growing polyps in your body in your early 20's or late teens. VERY RARE unless colon cancer runs in your family.
Agree, avoid Dr. Goggle!! You can diagnose yourself with anything with Dr. Google. A lot of information out there is out of date or just plain wrong. Unless you know where to look. Come here for questions & support. There is a wealth of information on this forum.
