How is skin cancer treated?

The treatment options for skin cancer are diverse and mainly include: 1. Surgical treatment: One of the primary treatments for skin cancer, involving surgical removal of the tumor, applicable to all stages of skin cancer. For small, superficial basal cell carcinomas with clear margins, excision with a margin of 0.5 cm around the tumor is generally sufficient. 2. Radiation therapy: Skin cancer is sensitive to radiation, especially basal cell carcinoma. Radiation therapy is suitable for areas with existing or potential lymph node metastasis and can also serve as an adjunct to pre- or post-operative treatment. 3. Chemotherapy: As a systemic adjuvant therapy, it is used for advanced stages or in combination with other treatment modalities. 4. Physical therapy: Including cryotherapy and laser therapy, which are used to ablate the tumor, causing necrosis, shedding, or vaporization. 5. Corrosive therapy: Involves the application of highly corrosive chemical agents for local cauterization or涂抹 (application). Selection of treatment should be based on a comprehensive evaluation of factors including tumor location and size, as well as the patient's overall health status.
