In Novemeber 2003 I was diagnosed with Stage 1 melanoma - .35 MM on my stomach. It was a Level 2. (It invaded the papilary dermis) The Dr. "cleared the margins" and told me to get a skin cancer screening every 6 months. Is this enough? Do I ned a PET scan? What else can I do?? Please help I am so scared and feel like the Dr. is not doing enough.
