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

Yes, a referral from your family physician or another specialist is almost always required to see an Radiation Oncologist like Dr. Peng 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 palliative care, and when might Dr. Peng 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. Peng 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.

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

After active cancer treatment finishes, Dr. Peng 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.

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. Peng can explain if targeted therapy is an option for your cancer.
