My daughter has joint pain, fatigue, paleness, bruising, petechiae and frequent colds along with on and off upper left abdominal pain below the ribs. my friend had leukemia as a child and had the same symptoms. could it be leukemia?

Once the idea of leukemia is raised, it is best to seek medical attention, a history, physical and laboratory evaluation, to be able to reassure. Most symptoms are not specific to a particular disease, and not all symptoms are found in any given disease. Best wishes.

The symptoms described are not specific enough to suspect leukemia. She deserves to have an adequate examination and screening lab works though.
