Aww, I'm sorry. It sucks losing a parent especially so young... because it doesn't seem like you're that old so in 2003 you must have been pretty young.
I've never lost a real parent to cancer, although my dad had a little cancer scare a couple years ago. I say "real parent" because I did lose a step-mom to cancer. I've also lost an aunt to cancer, a grandfather, a step-grandfather... I think my grandfather that died way before I was born also died of cancer. I have a brother that died of cancer at 5, but I never met him. That was a long time before I was born. My best friend had cancer but luckily he was able to get rid of it and is still alive..
