I had a mole to just "appear" on the back of my thigh, it was solid black and the size of a small deer tick. I went and had it removed/biopsied and it came back as malignant melanoma. I have had so many other moles/suspecious spots removed I've lost count. my dermotologist informed me, when something like this appears BLACK, get it checked immediately. THe longer it has time ot grow and spread, the wrose your chances. I cuaght mine in time, athough I do have a nasty 6 inch scar, plus I opted for hte lymph node sentinnel node biopsy. Common moles are brown in deed, but follow ABCD-Assemtry, Base, Color, Diameter...if a mole is two different colors or changes in size or color, oozes, of course your need these looked into. Skin cancer is nothing more than a mutated cell and you can even get this from a burn or skinning your knee as a child. Dogs get melanoma between their paws, the african american population get them yet, they are not sun worshipers like caucassions. Try not to worry about the report, just thank your lucky stars you caught this in time and something can be done about it! Keep us posted! PM if you'd like!
