I am an oncology nurse, but I still feel I am not getting straight answers about my cancer. Recently diagnosed with superficial spreading melanoma. Depth 0.74; stage Ia. Wide local excision complete; SNB negative; 5 nodes removed; 2 sentinel; 3 palpable. 7 additional moles removed; 5 negative; 2 results pending. My problem is every MD I see has a different idea of which of my dysplastic nevi should still be removed???? Would I benefit from either a PET scan or TA-90 testing?
