I had a 4cm polyp removed. Path came back reading tubulovillous adenoma with focal areas of high grade glandular dysplasia, no invasive malignancy identified. Margin appears free of the lesion. Surgeon says I will need yearly colonoscopy because it was cancer. My PCP says it was not. I have a follow up with GI in 3 weeks, but PCP states not necessary. I am confused. Not cancer, was cancer, see GI , don't see GI?
