My mother needs helping with her keloids that have grown fairly big. What can be done to remove them?

Integra. I use removal of the keloid followed by use of integra with a vac dressing. This is followed by a skin graft. Works ok but not 100%.
Several options. There are a number of treatments for keloids. We have had good luck with surgical removal of the entire keloid (for example, on the earlobe) and then a series of injections of steroid directly into the scar from the excision beginning 3 weeks postop and continuing every three weeks for a total of 3-4 injections. Other treatments include pressure and low dose radiation.
