Hematology is the treatment and study of disorders affecting the blood and bone marrow. Hematologists divide these disorders into two categories: malignant and non-malignant. Malignant conditions are any types that are true cancers; that is, they can spread, or metastasize.

These include all the varieties of lymphomas, leukemias, and myelomas.

Non-malignant types are no less serious. These include conditions of low red or white blood cell counts, low platelets, problems with blood clotting, sickle cell anemia, thalassemia (genetic blood disorders that involve abnormal production of hemoglobin), and myelodysplastic syndrome (chromosome damage to bone marrow).

At St. Luke’s Mountain States Tumor Institute (MSTI), physicians who specialize in hematology and oncology work to diagnose and treat these disorders. The Idaho Hemophilia Treatment Center, housed in the Pediatric Hematology and Oncology Clinic at St. Luke's MSTI, is the only center in Idaho that offers comprehensive care to people with hemophilia and other bleeding disorders.
