Cyst on my lip after treatments getting white

Patient: Hi,I am 33 year old woman. As you can see in the pic I had this weird bump (cyst) on my upper lip. Six months ago the doctor burned it with a device like a pen. The scar was small but deep. It was gone after a month and everything was fine. But now after six months around the sacar it’s getting white and I thinks it growing and it come into my lip which makes it very visible. Please let me know what it is, how much it grows and gets big and is there any treatment? PLEASE PLEASE HELP AS MY GP WAS NOT AT ANY HELP AT ALL
