Hello,
There are many procedures of mole removal like by shave or deep elliptical excision, excision with cauterization (a tool is used to burn away the mole) and
laser removal. Your dermatologist may choose excision with or without stitches, depending on the depth of the mole and the type of cosmetic outcome desired.
Laser removal has less chances of leaving scars but it is also not without side effects. Discuss the details of these procedures with your dermatologist.
