Hi Susan,
You can be sure your in good company here! There is a whole bunch with the same kind of surgical work. Congratulations on so many years of life after cancer. I too wondered why I never saw anyone else with the same scar.
You certainly are a beautiful wife and mother!
There may be someone here that can offer some comments on how they worked out the appearance thing. Personally I think you look fine

I sometimes wonder about how people see me and I also know that many times they don't even notice.
I try to think of it as a life achievment badge. Something to be worn with pride. The fact that they can see it means you are a winner!
Feel free to vent here if you need to
