What tests are usually done after a melanoma is discovered?

Biopsy,: First a biopsy followed by excision. Size of excision is dictated by size and depth of melanoma. Deeper lesions are accompanied by selective lymph node procedure. With deeper lesions a scan may be performed to rule out spread or metastasis as well as routine blood tests. For advanced cases an evaluation by an oncologist re medical treatment if necessary.

Surgery, evaluation: First priority is to excise the melanoma completely. Further treatment depends on how thick the tumor turns out to be. For very thin ones no further tests are necessary. For thicker ones a sentinel node study is often done, although this is controversial since a clear benefit has not yet been demonstrated. If there is evidence that the tumor has spread, a full-blown workup is ordered.
