The medical team at Seattle Children’s, a founding organization of Seattle Cancer Care Alliance (SCCA), has a long history of successfully caring for children and teens who have leukemia. Renowned specialists from Children’s and SCCA work together to improve your child’s quality of life and conquer leukemia.

This section covers information you'll need to know about chronic myelogenous leukemia (CML), also called chronic granulocytic leukemia, a slow-progressing blood disease that rarely occurs in children.

In CML, too many blood stem cells develop into a type of white blood cell called granulocytes, which do not become healthy white blood cells. These cells can build up in the blood and bone marrow leaving less room for healthy white blood cells, red blood cells and platelets. When this happens, infection, anemia or easy bleeding may occur.

Bone Marrow Transplant

If your child needs a bone marrow transplant, SCCA is the best place for it. Fred Hutchinson Cancer Research Center pioneered the use of bone marrow transplants as a treatment for leukemia more than 40 years ago. The Fred Hutchinson Transplant Program at SCCA was ranked first in outcomes in a multi-year study by the National Marrow Donor Program that measured one-year survival rates of patients at 122 transplant centers in the United States.
