@polianad22. You've provided an excellent description of the differences between surgeons in how they examine lymph nodes. I had endometrial cancer and interestingly what had been done for many years with breast cancer and examination of sentinel nodes had become standard practice at Mayo Clinic in 2019 where I had my surgery. My surgeon did the first option - frozen section that examined by pathology while I was still in the OR. In my case the sentinel nodes were negative so no other nodes were removed. At the sentinel nodes been positive then pelvic nodes would have been removed. All of this happens during surgery.

I expect that what you've described are different procedures at different cancer centers as practiced by different surgeons.

My GYNOncology surgeon at Mayo Clinic was very approachable and spent a lot of time explaining my cancer, the procedure, and answered my many, many questions.

So, are you going with the surgeon at Sloan Kettering? I expect that both surgeons would be very good but it is ultimately your decision in where and with who you feel most comfortable.

Is your surgery planned for soon? Would you feel comfortable sharing why you sought out a second opinion?
