Hi Kim,
I’m sorry you are having to go through this. Did you have ant symptoms before the colonoscopy or was this a screening colonoscopy? I had a similar experience. At age 61 in 2016, I had my first screening colonoscopy. I had no prior symptoms. A large sessile polyp was found about an inch above the cecum and could not be removed. The GI did biopsy it and tattooed it. Another flat polyp was found in the hepatic fold. The GI tattooed it but did not biopsy it. No other polyps were found. The sessile polyp was stage 0 carcinoma. I had a right hemicolectomy which removed both of the polyps. The sessile polyp was upgraded to stage 1 carcinoma with two “threads” just starting to penetrate the submucosa. Twenty lymph nodes were negative. For some reason for which I never received an answer, the other polyp was never biopsied, so I do not know if it was malignant or not. Surgery was curative and I have received no other treatment except CEA testing once a year and a colonoscopy every 3 years.
It will be 10 years May 9 that I am NED. I hope you have as good of an outcome. After all your tests are completed, you will have a better idea of what you are dealing with.
