Possible ear keloid, will United insurance cover the cost of removal? (photos)

I believe I may have a keloid on my ear behind the earlobe. I do have other keloid scars on my body on arm, back, chest and leg. My mother has keloid. The one on the ear is the newest - less than 2 years old and has been growing. It itches and burns at times but my concern here is mostly aesthetic. I am in the North Texas area. What would the experts here recommend? Will United insurance cover this and approximately what can I expect this to cost? Thanks for any help.
