I thought it would be worth mentioning for people who don't know what a c/s incision looks like........its pretty small compared to a tummy tuck. As far as I know a tummy tuck is hipbone to hipbone. And a c/s incision is anywhere from an inch or two (completely healed and faded) to 6 inches. So just because you are being cut with a c/s doesn't mean that the process is similar enough to kill two birds with one stone.
I know a c/s scar -- mine is TINY. I don't know enough about cosmetic/plastic (why plastic?) surgery to know the difference between liposuction and a tummy tuck, apparently. ;-)
