I got some possibly good news yesterday.
The first surgeon called, and she said that the Columbia U review of her slides showed that her diagnosis was accurate: she got that entire first tumour in her surgery.
She's asked the second surgeon to send over those slides so she can review them herself. As she put it, he's not a dermapathologist, and they may not have had one on staff at the hospital.
So my surgery this week has been postponed.
