Treatment methods of skin cancer mainly include surgery, radiation therapy and chemotherapy.1. Surgery is the preferred treatment method for skin cancer, and the cure rate can reach 90% with proper surgical excision. For those with confirmed regional lymph node metastasis, lymph node dissection should be performed.2. Radiation therapy, generally squamous cell carcinoma is moderately sensitive to radiation, basal cell carcinoma is particularly sensitive to radiation and has higher skin tolerance. It is mainly applied to patients with skin cancer in special areas not suitable for surgery, old and frail, and patients with contraindications to surgery.3. Chemotherapy, for patients who have already undergone surgical enlargement or radiation therapy, most of them are not allowed to undergo systemic chemotherapy. Systemic chemotherapy is mainly applied to patients with advanced cases who are not suitable for surgical resection or radiotherapy, and patients who are suspected to have residual lesions and metastases after surgery and radiotherapy. Since skin cancer is mostly limited and easily detected on the surface of the body, most of them will not affect the life if treated timely.
