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

Yes, a referral from your family physician or another specialist is almost always required to see an Radiation Oncologist like Dr. Zaza 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. Zaza can explain if targeted therapy is an option for your cancer.

What are common side effects of chemotherapy, and how does Dr. Zaza 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. Zaza 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.

What happens after cancer treatment is completed with Dr. Zaza?

After active cancer treatment finishes, Dr. Zaza will develop a survivorship care plan with you. This plan typically includes a schedule for follow-up appointments and tests to monitor for any signs of recurrence, management of any long-term side effects from treatment, recommendations for healthy lifestyle choices (diet, exercise), and coordination with your family doctor for ongoing general health care. The goal is to support your long-term health and well-being.

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

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

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