Hi: I have had skin cancer for a number of years - 25. I have had the dermatolgist do it both ways - the scraping and also cutting deeper to make sure they have a sample the has clean cells around it. As a precaution, I get my body checked fairly often - 2 to 3 times a year. The best advise I can give you is to be constantly aware of your skin and any markings that seem usually in size and texture. Good luck! Stay out of the sun and be protected!
