For patients with early-stage melanoma, if complete excision is achieved after surgical removal, some patients can be cured. Melanoma originates from melanocytes, which are malignant tumors. Melanocytes are distributed throughout the body, hence melanoma can occur in multiple parts of the body, primarily in the skin and mucous membranes, accounting for about 70% of cases. For early-stage melanoma, the main treatment method is still surgical excision. For patients with deeper melanoma infiltration, regional lymph node dissection is also necessary. After radical excision, treatments such as immunotherapy can be administered to consolidate the effects of the therapy, and some of the patients who complete these treatments can be cured.
