- Are consultations and treatments with Dr. Veilleux, an Hematologist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?
- 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 Hematologist such as Dr. Veilleux are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC 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 Régie de l'assurance maladie du Québec (RAMQ), Dr. Veilleux'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. Veilleux, an Hematologist?
- Yes, a referral from your family physician or another specialist is almost always required to see an Hematologist like Dr. Veilleux 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 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. Veilleux specializes in planning and delivering radiation therapy using techniques like EBRT, IMRT, SBRT, or brachytherapy. If this treatment is indicated for your type of cancer, Dr. Veilleux may coordinate with a Radiation Oncologist to ensure a multidisciplinary approach.
- 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. Veilleux can explain if targeted therapy is an option for your cancer.
