In most cases these are very rare or small because we have skilled doctors and excellent facilities that help reduce these risks. The commonest is worry is will the mark that replaces the mole look worse. This is almost guaranteed not to be the case as our doctors would always advise what is in your best interest. Yes occasionally there is a small scar or mark but these fade with time and will result in a much better appearance. Very rarely hypertrophic or keloid scarring can occur in certain people who are prone to these and we undertake aftercare treatment to help limit or treat these conditions.
