Focal cancer belongs to the early stage of cancer, and some of them can be cured by surgery. In most cases, after surgical resection of the lesion, cancer cells are found locally in the lesion, and the diagnosis of cancerous lesion is clear, but the cancerous lesion is relatively limited, radical surgery is feasible, and the cure rate is higher. If the focal cancer is early that metastasis occurs, such as lymph node metastasis, further lymph node dissection is needed to improve the 5-year survival rate. In addition, according to the postoperative pathological results, if the malignancy is relatively high or prone to distant metastasis, adjuvant radiotherapy, chemotherapy, targeted drug therapy, etc. can be used if necessary. Some focal cancerous lesions, which can be cured through radical surgery, should be treated in regular hospitals as early as possible.
