Whether nevus cancer can be cured or not is related to the level of invasion and whether the treatment is timely or not, etc. If early and active treatment is given, some patients can be clinically cured, but if it is found late or the treatment is not timely, it is usually difficult to be cured. 1. In the early stage of nevus cancer, the invasion level is relatively shallow, which can be treated by radical surgery. Surgery can remove the nevus up to the cutting edge without cancer cells remaining, and some patients can reach the level of clinical cure with postoperative radiotherapy. 2. If nevus cancer is found at a later stage, the invasion level is deeper, the patient has already had metastasis to the distal end and other organs, the scope of surgical resection is smaller, there are still cancer cells left in the local area, and there is no timely postoperative radiotherapy, this case usually cannot be cured, and is prone to recurrence. It is suggested that patients with nevus cancer should go to the hospital for consultation in time and be treated actively under the guidance of doctors, so as to avoid delaying the condition.
