Chronic myeloid leukaemia (CML)

CML affects about 60 people in Ireland each year. It is more common in men than women.

CML is treated with targeted therapies, chemotherapy, steroid therapy and stem cell transplants, depending on the type.

What is chronic myeloid leukaemia (CML)?

Chronic myeloid leukaemia (CML) is a slow-growing type of leukaemia (cancer of the blood) that affects a group of blood cells known as myeloid cells. Myeloid cells include a type of white blood cell known as granulocytes. With CML, the body makes too many granulocytes. These fill up the bone marrow, preventing normal blood cells from being made. This can leave you more at risk of infection or feeling tired and weak. How CML affects you depends on which phase it is in.

With the right medication, many people with CML have no symptoms and can lead a normal life.
