Do I need a referral to see Dr. Koll, an Radiation Oncologist?

Yes, a referral from your family physician or another specialist is almost always required to see an Radiation Oncologist like Dr. Koll for assessment or treatment of cancer or significant hematological conditions. This ensures that your primary care provider is involved in your care continuum and that you are directed to the most appropriate specialist for your specific situation. Cancer care programs often have centralized intake systems that manage referrals to ensure timely access.

Does a Hematologist only treat blood cancers?

No, Hematologists treat a wide range of blood disorders, not just cancers. This includes benign (non-cancerous) conditions such as various types of anemia (e.g., iron deficiency anemia, vitamin B12 deficiency, sickle cell anemia, thalassemia), bleeding disorders (like hemophilia or von Willebrand disease), clotting disorders (thrombophilia, deep vein thrombosis, pulmonary embolism), and issues with white blood cells (like neutropenia) or platelets (like ITP). Dr. Koll, if focused on hematology, can diagnose and manage these conditions.

What is immunotherapy and how does it work for cancer?

Immunotherapy is a type of cancer treatment that helps your own immune system fight cancer. It works by boosting or changing how the immune system works so it can find and attack cancer cells more effectively. There are different types of immunotherapy, including checkpoint inhibitors, CAR T-cell therapy, and cancer vaccines. Dr. Koll may recommend immunotherapy if it's an appropriate option for your type of cancer and will explain how it works and what to expect.

What does an Oncologist and/or Hematologist like Dr. Koll specialize in?

An Oncologist specializes in the diagnosis and treatment of cancer. This can include Medical Oncologists who use systemic treatments like chemotherapy and immunotherapy, Radiation Oncologists who use radiation therapy, and Surgical Oncologists who perform surgery to remove tumors. A Hematologist specializes in diagnosing and treating disorders of the blood, bone marrow, spleen, and lymph glands; this includes benign conditions like anemia and bleeding disorders, as well as malignant conditions (blood cancers) like leukemia, lymphoma, and myeloma.
