@swanpondside62 - these are very good questions have you been diagnosed with melanoma? Mohs micrographic surgery is a specialized technique primarily used for skin cancers like basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). It involves removing thin layers of skin containing the tumor, examining each layer under a microscope during the procedure, and repeating until no cancer cells remain. This allows precise removal of cancerous tissue while sparing healthy skin. For melanoma, its use is more limited but has gained traction for specific cases, particularly melanoma in situ (MIS, stage 0) or thin melanomas (Breslow depth < 0.8 mm), often in cosmetically sensitive areas like the face, scalp, or neck. Where is the lesion located? Since there are issues related to the effectiveness and location of the lesion. Would you like more information regarding the actual procedures their application and effectiveness?
