I'm sorry I'm 14 years old I don't really understand the terms behind it all. All I know that my dad has colon cancer two years ago and now it's spread back to his lungs. I also know that treatment that there giving him is not cure him this time, it's just to try and keep him here as long as possible. I hate the thought of him not seeing me get married or even go off to university and all my friends keep saying you are so strong or he has chance. But that chance is a 10% chance when it used to be 60%. I'm sorry if I couldn't answer any of your questions I honestly just don't know. This doesn't mean that my parents are keeping stuff from me or hiding the truth or anything because I spoken to the doctor myself and he told me everything that my parents basically told me. I'm trying to keep strong but I know there's a big chancemy future is about to get ugly and I need to prepare myself for that too.
