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

Yes, a referral from your family physician or another specialist is almost always required to see an Radiation Oncologist like Dr. Gaudet 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.

What can I expect at my first appointment with an Oncologist/Hematologist?

Your first appointment with Dr. Gaudet will be comprehensive and may last an hour or more. It will involve a detailed review of your medical history, family history of cancer, current symptoms, medications, and any previous tests, imaging results (CT, MRI, PET scans), and biopsy reports related to your diagnosis. He will likely perform a thorough physical examination. The main goals are to confirm your diagnosis, discuss the type and stage of your condition (if applicable), and outline potential treatment options. This is a crucial time to ask questions, and you are encouraged to bring a family member or friend for support and to help take notes. Dr. Gaudet will explain the proposed treatment plan, including goals, benefits, potential side effects, duration, and what to expect moving forward. Further tests may be ordered.

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. Gaudet, if focused on hematology, can diagnose and manage these conditions.

How is cancer care typically coordinated when seeing Dr. Gaudet?

Cancer care and complex hematology care often involve a multidisciplinary team (MDT) of specialists working together. This team may include medical oncologists like Dr. Gaudet, surgeons, radiation oncologists, pathologists, radiologists, specialized oncology nurses, pharmacists, social workers, dietitians, genetic counselors, and palliative care specialists. Regular team meetings (often called tumor boards or MDT meetings) usually occur to discuss individual patient cases and develop comprehensive, coordinated treatment plans. Dr. Gaudet works collaboratively within this team to ensure you receive holistic and well-managed care.

How will treatment decisions be made for my condition by Dr. Gaudet?

Treatment decisions in oncology and hematology are highly personalized and made collaboratively. Dr. Gaudet will consider many factors, including the type and stage of your cancer or blood disorder, your overall health, genetic markers of the disease (if applicable), current treatment guidelines, and importantly, your personal preferences and values. Often, cases are discussed in multidisciplinary team meetings (tumor boards) with other specialists to ensure a comprehensive approach. You will be an active participant in this decision-making process.
