What kind of moles need surgery? Larger and deeper moles (3mm or more, raised) need to be removed surgically. This is because it is very unreliable to remove such a mole completely by the naked eye, experience, or even by hand. Most of them recur after a number of months or years. Even if the laser removes it at once, the formed trauma is large and deep, and after healing it is a flaky scar, which is very aesthetically displeasing. A special reminder is to pay attention to moles located on the soles of the feet, under the fingernails, and in the mucous membrane of the upper and lower lips, because these areas are often rubbed and moles have a higher chance of malignant change. Will scars remain after surgery? Surgery will definitely leave scars. However, after cosmetic dermatologic surgery, a linear scar is left behind, which will gradually become lighter and lighter after three months until it finally does not affect the beauty. It is more effective if combined with some scar inhibiting creams. How long will the scar be after excision? The scar will be longer than the long axis of the mole for the following reasons: 1. The mole should be cut 1-2mm outside the edge of the mole to ensure a clean excision; 2. The two ends of the incision should be properly extended to become a sharp angle in order to avoid the skin from sticking up after suturing (commonly known as cat ears); the final result depends on the recovery of the incision, not the length of the incision. A longer incision is not obvious if it recovers well; a shorter incision is not ideal if it recovers poorly and forms an obvious scar. Can a mole recur after removal? Recurrence is very rare. The surgery is performed under direct vision to remove all the lesions that can be seen, and there are pathological examinations after the surgery to see if the edges are clean under the microscope, so recurrence after surgery is very rare. Even if there is a recurrence, don’t be nervous, it is just a small part of the mole cells that were not cut, and if there is no change in the nature, it can be completely removed again. Will surgery stimulate the mole to become malignant? Surgery can remove the pigmented mole, and there are no more mole cells after surgery, so there is no question of stimulating it to become malignant.
