The time for melanoma to progress to an advanced stage is not fixed, and currently, the internal oncology community views melanoma as a highly malignant tumor that develops rapidly. Melanoma is a malignant tumor originating from melanocytes and can occur in multiple parts of the body, with the most common sites being the skin and mucous membranes, accounting for about 70%. Once diagnosed, patients with melanoma are still primarily considered for surgical treatment. For those who have undergone surgery, immunotherapy can be used for consolidation. For patients who are not candidates for surgery at the time of diagnosis, systemic treatments such as chemotherapy and immunotherapy are generally adopted to control the progression of the disease.
