My breast reduction keloids grew back after excision, what is the appropriate treatment? (Photo)

I had my initial breast reduction March 2016 with axillary fat removed. After surgery I developed thick purple keloids on the both sides of my breast, armpit and nipples. Tried silicone sheeting and creams. November of 2017 surgeon removed the keloids on my sides and my armpit. I did embrace and creams, keloids have grown back to the size they were. They are very painful. I want to re excise the keloids, but also want combination therapy including corticosteroid injections, radiation therapy. Is there a specialist in Dallas/ Fort Worth?
