• Multiple Myeloma: A cancer of plasma cells, a type of white blood cell in the bone marrow that produces antibodies, leading to bone damage and other complications.
• Myelodysplastic Syndromes (MDS): A group of diverse bone marrow disorders in which the bone marrow does not produce enough healthy, mature blood cells.

Common Cancers (Solid Tumors) Treated

• Lung Cancer (Non-Small Cell & Small Cell): Cancers originating in the lungs, treated with chemotherapy, targeted therapy, immunotherapy, and/or radiation based on type and stage.
• Head and Neck Cancers (Oral Cavity, Pharynx, Larynx - Medical Oncology aspects): Cancers arising in the head and neck region, where medical oncologists manage chemotherapy, immunotherapy, or targeted therapies as part of a multidisciplinary team.

Are consultations and treatments with Dr. Chung, an Radiation Oncologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations, diagnostic tests (like biopsies, imaging reviews), chemotherapy, immunotherapy, targeted therapies, radiation therapy planning and delivery, and management of blood disorders by a licensed Radiation Oncologist such as Dr. Chung are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor or another specialist is in place. Specific drug coverage for newer therapies can vary by provincial formularies and may require special authorization. It's always recommended to discuss coverage specifics with Ontario Health Insurance Plan (OHIP), Dr. Chung's office, the hospital's patient financial services, or the cancer care navigation services at the treatment facility.

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

Yes, a referral from your family physician or another specialist is almost always required to see an Radiation Oncologist like Dr. Chung 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 is targeted therapy in cancer treatment?

Targeted therapy uses drugs or other substances to identify and attack specific types of cancer cells with less harm to normal cells. These therapies work by targeting specific genes or proteins found in cancer cells or cells related to cancer growth, like blood vessel cells. Genetic testing of the tumor is often done to see if a targeted therapy is likely to be effective. Dr. Chung can explain if targeted therapy is an option for your cancer.

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

Cancer care and complex hematology care often involve a multidisciplinary team (MDT) of specialists working together. This team may include medical oncologists like Dr. Chung, 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. Chung works collaboratively within this team to ensure you receive holistic and well-managed care.

What is palliative care, and when might Dr. Chung discuss it?

Palliative care is specialized medical care focused on providing relief from the symptoms and stress of a serious illness, like cancer or advanced blood disorders. The goal is to improve quality of life for both the patient and the family. It can be provided at any stage of illness, alongside curative treatments, not just at the end of life. Dr. Chung may discuss palliative care if you are experiencing significant symptoms, to help manage pain, fatigue, nausea, anxiety, or other issues, and to provide an extra layer of support.

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

Treatment decisions in oncology and hematology are highly personalized and made collaboratively. Dr. Chung 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.

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

What are common side effects of chemotherapy, and how does Dr. Chung help manage them?

Chemotherapy can cause various side effects, which differ depending on the specific drugs used, the dose, and individual patient factors. Common ones include fatigue, nausea, vomiting, hair loss, mouth sores, changes in appetite, diarrhea or constipation, and increased risk of infection due to low blood counts. Dr. Chung and the oncology nursing team will discuss potential side effects of your specific treatment plan in detail and will actively work to prevent and manage them with medications (e.g., anti-nausea drugs, growth factors to boost blood counts), supportive care advice (nutrition, hydration, rest), and regular monitoring. Open communication about any side effects you experience is very important for effective management.
