Worried that I have leukemia?

It might just be that you are scaring yourself. Other symptoms of leukemia include frequent bruises and fatigue. Has anyone in your family had leukemia? I think that leukemia can only passed down through genes, so if nobody in your family had it, then you probably don't have it. If you're really concerned, you should see a doctor and request a blood test. You might have something else other than leukemia.
