I was diagnosed with ovarian cancer at 20 years old. I had to have major abdominal surgery 13 years ago to remove 12cm tumor. Since then I've had 2 kids and my last baby was two years. Since then I've had constant pain on the sides of stomach and lower back. When I lean back I get these bulges on both sides of my stomach. What could be causing it and if there is any type of plastic surgery that could fix it. I would love a nice flat tummy. I haven't had one since I was 20 years old : ( Thanks
