Keloids tend to recur even after surgery. If they have recurred, my suggestion would be to have it surgically removed again and then injected immediately with steroid and 5-FU a medication that is integrated into the injection. I have my patients do this for 3 monthly visits after the excision of the keloid in combination with a laser treatment (Excel V) as well as topical silicone gel (Biocorneum). It is a process, but that is the best way besides post procedural radiation, to prevent recurrence. Nobody can promise it wont come back, but this is your best option. We would gladly see you in the office for a consult anytime. You should seek someone with experience in treating these difficult type of cases. I wish you the best of luck, Dr. Emer.
