How can I get rid of my keloid scar? (Photo)

It itches and keeps on getting bigger. A year after I did my breast the keloid scar appeared and it is ruining my life. I hate it and I can't wear tops without bras because it prints through. I had tubular breast before and my doctor said the only the incision he can make is through my areola to correct my deform breast. I wish the incision was made under my arm to avoid this. PLEASE HELP!
