Well, from what you say it's a symptom? All the things that cause it. My uncle didn't do any of that and he had cancer. I also had cancer,I was born with it. It was called "Infant Tile Fibro Sercoma". I believe that's how it's spelled. How could it be a sympton? I don't think it's a disease either though. It's just something that happens to the unlucky? Kemo/Chemo, not sure how it's spelled either, is based on luck also. Some people survive it, some don't. It's all they have though. Luckily, it saved me, and im glad I was born with it, so I don't remember any of it. Search up "Kids Kicking Cancer" It's a program to help kids mainly. It may be found in other places, but I know it's in Louisiana.
