Any woman considering a career in surgery (hell, men should read it, too) should read "A Woman in a Surgeon's Body" by Joan Cassell. She is an anthropologist whose culture of interest is surgery. I had a pretty schizo reaction to the book: On the one hand, it scared the bejeezus out of me. On the other, I'm thinking how important it is to get more women into surgery.
Other books: The Blood of Strangers (by an ER doc--the writing is OK but the stories are interesting albeit not polished). Healing Lessons is another book, about a GI oncologist whose wife contracts the cancer he specializes in ... it's ghost-written (although told in 1st person), but is a very moving story.
