As a health anxiety sufferer, this is my worst fear. I went to the dermatologist as I have been getting regular check ups. I had a lot of unprotected sun exposure as a teenager and in to my 20s...that's what we did back in the 70's and early 80's...sunscreen? SPF 5? Anyway, he saw one spot on my scalp that was "darker " than the others and a mole on my back (small) that was dark with irregular borders. He removed them, and I now am in Hell Week waiting for the results. I have had "atypical moles" removed before, and he felt this was the most likely scenario, but wouldn't be forthcoming which makes me nervous. Do they only biopsies when they suspect cancer?
