hello everyone. i am convinced i have a cancer such as leukemia. I am NEVER sick and within a week i had a chest infection which went away and now it seems as if i have a sinus infection because i now have blood in my mucus and quite a bit of blood. are these symptoms of cancer? I also have had a very poor appetite. i eat one meal a day and thats it. i cannot go to a doctor, i have no health insurance. what are the chances. im 22 years old. also am noticing that i got a bruise from hitting my leg a couple days ago.
