Tummy tuck scar 12 months post op. (photos)

Unfortunately scarring is somewhat unpredictable and it's management can be challenging.  Radiation treatment can be very effective for problematic keloid scarring.  The procedure involves surgical excision followed by three radiation treatments in consecutive days, typically starting the day of the procedure.  I have done this successfully many times with problematic keloid scars.  I typically use this as a last resort, after other methods such as steroid injections and pressure therapy have been unsuccessful.   I have not used radiation treatment after cosmetic procedures, however, so I cannot comment about the cost or if insurance will cover the treatment.  I would recommend Embrace scar therapy if you do have a scar excision.

I would just be patient.  I think radiation is a unreasonably agressive suggestion.  The scar will mature over time
