You are a survivor and should be PROUD of that scar. Don't be afraid to show it off and if asked, tell them what it's from. believe it or not, it gives people hope that they too can have that chance to survive if needed. I know because I also have scars. They are on my chest from the heart transplant I had 18 months ago. I am very proud of that and i'm not afraid to show them. You see, I am a nudist, so a lot of people see my scars, some do ask and I don't mind telling them.
