Apparently not an exact science.

I had to go for two biopsies yesterday on moles/dark spots that I've had since I was first diagnosed with melanoma almost four years ago, and which haven't changed in all that time. Why, after all this time, the sudden decision to biopsy them? If there was another dermatologist that lived within 100 miles of here, I think I'd change. Oh well, results in two weeks.

(Note: the last two she decided to biopsy a year or so ago turned out to be nothing.)
