How Safe Is Surgical Birthmark Removal?

H im,e ma I answer your health queries right now ? Please type your query here... Hi i had a birthmark on my forehead in the centre of it since birth. I got it removed when i was 10 which was 12 years ago and the scar left is still very prominent. And appears to be getting longer i.e. coming down onto my nose? i would like to get it removed through a dermatologist is this possible?
