What procedure is recommended for keloid removal and nipple split after nipple piercing? (Photo)

I once had a nipple bar ring and the bar got caught on my bracelet which lead to my nipple splitting in half and a keloid has developed on the side. This happened four years ago and the keloid has grown in size. What procedure is recommended? Could this be accomplished with out injections? I give birth later this year and want to breast freed, will I be able to? What’s the healing time for this procedure? Should I wait till after I give birth?
