Web1-4 mm thick melanoma is called intermediate thickness Over 4mm in thickness is called a ‘thick’ melanoma The Breslow thickness is the main measurement used to decide what further treatment is needed and guides the surgeon as to whether a sentinel node biopsy is required and what width a wide local excision should be. WebThickness of <1mm: At this level, it is very unlikely that the melanoma has grown deep enough for any of the cancer cells to break away from the primary tumor and spread.
