You’re welcome. I am in Seattle (UW Medicine system), and did not go to Mayo. I imagine your question is really about the skill of the doctors who perform these colonoscopies on patients such as us. SSA’s require skill to remove, and should I move somewhere new in the future I will certainly look for medical providers with experience in finding and managing such sessile adenomas. The Philadelphia area has great health care (for example the Penn system) and working in our favor I would think is that population centers are better resourced and see more cases like ours.
