Hello,
There are two methods of mole removal i.e excision followed by cutting and excision with cautery. Although laser removal has been tried for moles, it is not usually the method of choice for most deep moles because the laser light doesn't penetrate deeply enough.
This depends on the depth of mole and the type of cosmetic outcome desired.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
