First of all, you are not stage 3. You would only be designated as such if you have any lymph node involvement. You are on the cusp of needing a sentinel node biopsy, usually .76 and up is the point of needing one. In fact, many would find you diagnosis as fairly low risk. So there is no real rush to get this done as the surgeon indicated. You may want to get a second opinion from a center that does see a lot of melanoma patients. I hope this helps you. Please be sure to read more on this website about being newly diagnosed, etc. above in the BLUE section..
