Seeing a hematologist does not necessarily mean you have cancer. Hematologists are specialized doctors who diagnose and treat a wide range of blood disorders, including but not limited to non-cancerous conditions like anemia, bleeding disorders, clotting disorders, and immune system deficiencies. However, they also treat cancerous conditions such as leukemia, lymphoma, and myeloma. If your primary care physician refers you to a hematologist, it is to ensure a thorough evaluation of your blood-related health concerns, which may or may not be related to cancer. Hematologists work closely with other specialists to provide accurate diagnoses and develop personalized treatment plans based on individual needs.
