Third time's the charm?

So, the pathologist now says the verges are clear (from the arm lump third surgery). From the doctor, I thought I understood that this was benign. Apparently not really; it was a sarcoma (at least from one of the pathologist calls). That's malignant, the doc now tells me. But with little chance of metastasizing, apparently. Confusing, isn't it?

But focus on clear verges, eh?
