Do I need a referral to see Dr. Lheureux, an Medical Oncologist?

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

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

After active cancer treatment finishes, Dr. Lheureux 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. Lheureux 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. Lheureux 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 kind of supportive care is available during cancer or hematology treatment with Dr. Lheureux?

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. Lheureux and the healthcare team at hospitals or cancer centres in Toronto can connect you with these valuable resources.
