The incidence of skin cancer is increasing, the causes of which are sun exposure, chronic inflammatory stimulation, genetic mutation, physical stimulation, etc. Some of the causes are still unclear. As for the treatment, since it is cancer, the characteristics of this disease are the same as other cancers, which can be local recurrence and distant metastasis, but there is no need to worry too much, most of the patients with skin cancer can be cured. The surgical procedure should conform to the tumor surgery standard. This way patients can benefit more. For example, if the tumor is 3 centimeters, according to the clinical and pathological need to remove 3 centimeters from the edge of the tumor, then the safe range of resection should be 9 centimeters in diameter, which has a problem that requires skin grafting, which requires choosing the skin extraction area and striving for one-time skin graft survival, which requires clinicians to have rich experience. If the skin graft does not survive, the patient’s hospital stay will be prolonged, the economic expenditure will have to increase, and a second skin graft will be required, causing pain to the patient. The failure of the implant does not mean that the surgery is a failure. There may be various reasons for the failure of the implant, such as severe diabetes, original skin disease, etc. However, doctors should know which surgery can be done and which surgery cannot be done, and the discretion to grasp this scale lies with doctors. Many doctors do not have the certainty and experience of skin graft survival, so they try to close the wound directly and ignore the scope of surgical safety, which is not right and should not be done. Skin cancer generally does not require radiotherapy and chemotherapy, and can be treated by immunotherapy or Chinese medicine.
