My 6year old brother was diagnosed with Non hodgkin's lymphoma in June 2009. He has finished his chemo but is still having to go back in. I caught a bug from school and I was ill and had a cough. But because I was always near my brother, he caught it. But because his immune system was low it hit him worse and his temperature was up and he was really unwell. My dad called the ward and he had to go back to hospital. I'm really upset.
