Skin cancer is a malignant tumor of the skin. It has different names according to the origin of tumor cells, including epidermis, skin appendages, skin soft tissue, peripheral nerves, melanocytes, skin lymphoreticular tissue and hematopoietic tissue. Others are metastatic tumors that have metastasized to the skin from other tissues

Skin cancer is easier to treat the earlier it is detected, so it is important to understand the symptoms of skin cancer. Generally speaking, the symptoms of skin cancer are very insignificant in the early stage, and some erythema or some chronic small ulcers may appear. Most skin cancers develop slowly, with ulcers and ulcers appearing as the disease progresses. Once these symptoms appear on the skin, be sure to go to the hospital for treatment in time.

Skin malignant tumors are superficial, and there are many treatment methods, such as surgical resection, radiotherapy, cryotherapy, laser therapy, local drug physical corrosion therapy and chemotherapy. Chemotherapy is adjuvant therapy and late-stage palliative therapy suitable for use in combination with other treatments. The application can be selected according to the location and size of the cancer, the general condition of the patient, and the degree of the cancer. The principle of treatment is to remove the tumor, maximize function preservation, and reduce cosmetic damage.

1. Surgical therapy
It is suitable for all stages of skin cancer, and the tumor can be completely removed by surgery.
2. Lymph node dissection
Selective regional lymph node dissection after surgical resection of squamous cell carcinoma is difficult to decide. Prophylactic dissection is not the most necessary option, and the best decision should be made based on the patient's age, cancer site, degree of invasion, and cancer cell differentiation.
