Average cost for epithelial ingrowth treatment?

I cannot find any information about the cost of surgery to remove epithelial ingrowth but I am very concerned since I have read a few horror stories about it coming back 4 times. I know most of you would have to be reluctant to guess but I would really appreciate it. I'm not going to quote you, I'm just hoping I can quit worrying about the worst case scenario. I'm in the midwest (if you know prices so well that you can adjust regionally lol). Thanks!
