A hematologist is a doctor who specializes in blood disorders and related diseases including those affecting the bone marrow, spleen, and lymph nodes. Many hematologists are also trained as oncologists, giving them additional expertise in cancerous blood disorders. These doctors are called hematologist-oncologists (often abbreviated Hem-Onc). If you are diagnosed with an hematological condition, it is important to get the best treatment to make sure you can stay healthy.
