Why my Mole Comes Back After I Did a Lazer Removal?

a Mole or "melanocytic nevus" is basically a collection of skin pigment producing cells. If you have a collection in one area, you get a Mole! 

There are many types of moles, but of the most common "benign" ones, there are three main types. The type of mole is determined by the depth these skin pigment producing cells are located in your skin. Sorry to get long winded, but i think it will help

Type 1: Junctional - These are usually flat and are located closer to the skin surface, so you can usually see them really well, but as I mentioned, they are not raised so most people dont ask to have them removed. 

Type 2: compound - These are raised like a bump and a common one to be removed. The pigment cells are located a bit deeper in your skin but still look very dark. 

type 3 - Indradermal - these are the deepest and are often not brown/black as they are so deep you only see a bump that looks skin color. 

Obviously, the second type is the most common to remove. The balance we take with mole removals is that, we want to get as much of the pigment cells removed however, not dig too deep into the skin as you will get a scar. All it takes is a few pigment cells to remain (we may not see them) for the mole to return. Its not uncommon for this to happen, as I mentioned we dont want to trade a mole for a scar. 

The final thing I will mention, is any new mole or return of a mole should be assessed by an FRCPC/FRCSC in canada or board certified physician in the USA as you need to ensure it is nothing more worrysome. The odds are it is not, but its always better to get it checked. 

Hope this was helpfull. 

We typically advise patients to undergo excision of moles as the chance for recurrence is quite low. Perhaps you will now need excision since the mole has recurred. Raffy Karamanoukian, Los Angeles
