1 day after mole was shave biopsied for cosmetic reasons, there is a blackish/blue spot left over.dr never thought melanoma but now i'm worried!cause?

Post procedure: What you are describing sounds like a local tissue response to the procedure you had. The biopsy results will confirm what the lesion was.

Information: What you see is what is left over from the procedure. The entire mole should be removed. Generally it is usually possible to tell a good mole from a bad one, but not always. Many authorities believe that mole removal should always be complete. Gemerally a shave biopsy does not remove the deep layers. Treatment and prognosis of melanoma depend on precise thickness measurement.

Please consult with a Dermatologist Doctor who can give you a through examination and the correct recommendations and treatment. If you are not confident in your Doctor see another for a second opinion.
