The appearance of small black dots in the local area after mole removal is a recurrence of moles, which can easily occur in all clinical applications of mole removal. Some patients may think that the doctor did not remove the mole cleanly at that time, but in fact, when the doctor removes the mole, he or she cannot tell from the naked eye how large the mole cells are. Because mole cells are very small, once 1 or very few mole cells are not removed cleanly, recurrence can easily occur. Therefore, if small black dots appear again, patients can consider mole removal again, but there should be a clear time interval between the 2 times of mole removal and wait for the wound to recover well before proceeding.
