It may recur, and the probability of recurrence depends on its stage. The probability of recurrence is smaller after clean excision in early stage and slightly larger in non-early stage. 1. Early stage: Early stage basal cell carcinoma can be excised cleanly and most of them can be cured, and the probability of recurrence is smaller. 2. Non-early stage: If the basal cell carcinoma is not in early stage, even if it is removed cleanly by surgery, there is a greater possibility of metastasis and recurrence after surgery. After surgery, radiotherapy and chemotherapy can be used to improve the cure rate and prevent recurrence and metastasis. The higher the differentiation degree of the tumor, the better the safety range of the lesion, the higher the possibility of clean excision and the lower the probability of recurrence, on the contrary, the lower the differentiation degree, the higher the degree of malignancy and the higher the probability of recurrence.
