I used to feel sick and tired, and sometimes I had a blood nose and sore legs. I went to see my doctor and after he did some tests he said I have leukaemia. My doctor told me all about leukaemia and why it had been making me feel sick. You can find out too in the cartoon below.

He said that I didn't do anything wrong to get leukaemia and that you can't 'catch' it from someone who has it. My doctor said there are special medicines and people to help me get better.
