I have random bruises and it doesn't hurt, is this leukemia?

Not likely: Probably not. This could be due to diet or medication you are on, or a blood disorder. Have your parent or guardian make you an appointment with a doctor to have this checked. Good luck!

Needs investigation: Bruising can be a symptom of many different things, not just leukemia. Besides discussing this with you to get more information, your doctor will probably want to do some bloodwork, for example, to count different types of bloodcells and to check how fast (or slow) your blood clots. Contact your local physician to get this looked into.

Not necessarily : Can be low platelets from many causes Or any inherited or acquired coagulation issue Any drug or viral infection
