I'm a 13 year old girl and I wasn't be able to eat in past few days, my stomach hurts real bad, and I my legs are weak and I couldn't really walk much lately. My parents were concerned so they took me to the doctor yesterday and I was complaining about my stomach is hurting and I haven't been walking much because my legs been weak lately and she felt my stomach and said it was hard and I told her I wasn't been able eating, then she got concerned and I got referred to an oncologist because my stomach felt hard it could be a possibility of a tumor, so I have to go tomorrow. I'm scared to death that it could be cancer I don't know what to do. There's people with cancer had chemotherapy and has side effects like hair loss and such, I don't want to lose my hair I care too much about my appearances. I'm crying and I don't even know what to do anymore. I don't know why my stomach was hard....I've been healthy all my life, I exercise every single day and I'm on the school soccer team, and I never even eat fast food at all. If I do have cancer, I won't be able to play soccer at all when school starts back and I'll probably miss school as well. I'm scared and I'm too young to have serious things wrong with me especially I eat healthy and I exercise every day. I don't know what to do anymore. What should I do?
