Dr. Jasper See Yin Yuen

Dr. Jasper Yuen has expertise in managing a wide range of conditions, including:

Common Areas/Cancers Treated with Radiation Oncology

• Thoracic Cancers (e.g., Lung Cancer, Esophageal Cancer, Mesothelioma): Using radiation therapy to treat cancers within the chest cavity, often combined with other modalities.
• Head & Neck Cancers (e.g., Laryngeal, Pharyngeal, Oral Cavity): Utilizing radiation therapy as a primary treatment, or in conjunction with surgery and/or chemotherapy for cancers of the head and neck region.
• Central Nervous System (CNS) Tumors (Brain & Spine): Employing precise radiation techniques to treat benign and malignant tumors of the brain and spinal cord.

Hematologic Malignancies (Blood Cancers) Treated

• Chronic Lymphocytic Leukemia (CLL) / Small Lymphocytic Lymphoma (SLL): A type of cancer that starts from white blood cells (lymphocytes) in the bone marrow, typically slow-growing.
• Myeloproliferative Neoplasms (MPN) (Polycythemia Vera, Essential Thrombocythemia, Myelofibrosis): A group of chronic blood cancers where the bone marrow produces too many red blood cells, white blood cells, or platelets.
• Acute Lymphoblastic Leukemia (ALL): A type of cancer of the blood and bone marrow that affects white blood cells called lymphocytes, common in children but also occurs in adults.

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.
• Neuroendocrine Tumors (NETs): A diverse group of tumors that arise from cells of the endocrine (hormonal) and nervous systems, treated with various systemic therapies.
• 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.

This list provides examples of common conditions treated and is not exhaustive. Cancer and blood disorders are complex, and treatment is highly individualized. For personalized advice, please discuss your specific situation with Dr. Jasper Yuen or your referring physician.

• Image-Guided Radiation Therapy (IGRT): Utilizing advanced imaging during treatment delivery to precisely target tumors and adapt to changes, while minimizing exposure to healthy tissues.
• Total Body Irradiation (TBI) - Component of Stem Cell Transplant Regimens: Radiation therapy delivered to the entire body, often used as part of the conditioning regimen before a bone marrow or stem cell transplant.
• Stereotactic Body Radiotherapy (SBRT) / Stereotactic Ablative Radiotherapy (SABR) / Stereotactic Radiosurgery (SRS): Delivering highly focused, high-dose radiation to precisely targeted tumors or lesions in the brain or body, often in a few treatment sessions.
• Genetic Counseling & Testing Referrals for Hereditary Cancer Syndromes: Assessment of family history and risk factors, and coordination of referrals for genetic counseling and testing for inherited predispositions to cancer (e.g., BRCA).
• Performance Status Assessment & Treatment Eligibility Evaluation: Evaluating a patient's overall fitness and ability to tolerate specific anti-cancer treatments.
• Second Opinion Consultations for Cancer & Blood Disorders: Providing expert second opinions on complex diagnoses and proposed treatment plans to ensure informed decision-making.
• External Beam Radiation Therapy (EBRT) - 3D Conformal, IMRT, VMAT: Developing precise, individualized plans for delivering radiation using external machines (e.g., linear accelerators) with techniques like Intensity-Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT).

Are consultations and treatments with Dr. Yuen, 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. Yuen 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. Yuen'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. Yuen, an Radiation Oncologist?

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

Why might I need a bone marrow biopsy, and what does it involve if Dr. Yuen recommends it?

A bone marrow biopsy and aspiration are procedures used to collect and examine bone marrow, the soft tissue inside your bones where blood cells are made. Dr. Yuen might recommend this test to diagnose or monitor various blood disorders, including leukemias, lymphomas, myeloma, anemias, or infections. The procedure is usually done on the back of the hip bone under local anesthesia. A needle is used to withdraw a small sample of liquid marrow (aspiration) and a small core of bone marrow tissue (biopsy). You may feel some pressure or brief pain.

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

Your first appointment with Dr. Yuen 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. Yuen will explain the proposed treatment plan, including goals, benefits, potential side effects, duration, and what to expect moving forward. Further tests may be ordered.

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

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

What kind of supportive care is available during cancer or hematology treatment with Dr. Yuen?

Supportive care is a crucial part of treatment, aiming to manage symptoms, reduce side effects, improve quality of life, and address emotional and practical needs. This can include effective pain and symptom management, nutritional support and counseling, psychological support (counseling, therapy), social work services for practical and emotional support, physiotherapy or occupational therapy, access to patient support groups, and spiritual care. Dr. Yuen and the healthcare team at hospitals or cancer centres in Mississauga can connect you with these valuable resources.

What is Radiation Oncology and when is it used?

Radiation Oncology is a medical specialty that uses high-energy radiation (like X-rays, gamma rays, or charged particles) to damage or destroy cancer cells and shrink tumors. It can be used as a primary treatment, before surgery (neoadjuvant), after surgery (adjuvant), or in combination with chemotherapy. It can also be used for palliative care to relieve symptoms. Dr. Yuen specializes in planning and delivering radiation therapy using techniques like EBRT, IMRT, SBRT, or brachytherapy. If radiation therapy is indicated for your cancer, Dr. Yuen will coordinate your treatment plan to ensure optimal outcomes.
