Is There Any Hope for Removing a Badly Indented Scar?

The scar is about 7 inches long and 1/3 of an inch above my bellybutton. It's about 11 years old, slightly raised, and similar to the color of my own skin, maybe slightly lighter. The scar isn't that bad, the real problem is that I've had it since I was quite young and it hasn't stretched with the rest of the skin on my abdomen. My stomach above the scar comes out about half an inch, and a full inch or more below. Could surgery fix this? I'm not overweight and I don't think toning up would help.
