I didn’t answer one of your questions.

During surgery, they will usually send tissue out to The pathologist who will examine the tissue and see if it has cancer in it. They will then let the surgeon know whether or not it is clear and if not, the surgeon will cut some more into the tissue to try to get clean margins.

The question is, does your surgeon have this capability?. I know a pathologist who used to work in a hospital, and that was part of his job, to examine tissue as The operation was going on.
