The physicians who practice as part of the Hematology-Oncology Associates group practice are all experts in blood disorders and treating cancer with drugs. Medical oncology is the diagnosis and treatment of all types of cancer, as well as benign tumors. Medical oncologists select and administer chemotherapy for malignancy, and consult with surgeons and radiotherapists regarding other cancer treatments. Hematology is concerned with diseases of the blood, spleen and lymph glands, focusing on such conditions as anemia, clotting disorders, sickle cell disease, hemophilia, leukemia and lymphoma. Hematologists perform special types of transfusions and biopsy bone marrow for analysis.
