Is it okay to remove junctional nevus? It depends on the specific changes of junctional nevus and the size of surgical excision. If the junctional nevus has not developed into malignant tumor and the scope of surgical excision is large enough, in this case, after surgical excision of the junctional nevus, the effect of complete cure can be achieved without causing residual tumor cells and recurrence. Secondly, if the junctional nevus has developed into malignant tumor, the scope of surgical excision is small, and the pathological results suggest that cancer cells can still be seen at the cutting edge after surgical excision. In this case, the surgical excision of junctional nevus does not achieve the purpose of complete cure, and there are still residual tumor cells, so patients need further radiotherapy or even second surgery to completely remove the tumor cells in the body and avoid the recurrence of tumor cells.
