Meet the Team: Marvelle Koffler Breast Centre

The clinical team in the Marvelle Koffler Breast Centre (MKBC) at Mount Sinai Hospital is made up of world-class leaders in breast cancer diagnosis and treatment. We ensure each patient is cared for in a comprehensive manner, from the physical to the psychosocial.

A radiologist is a doctor that specializes in interpreting images of the body to diagnose and treat medical conditions. In the Marvelle Koffler Breast Centre, radiologists play a very important role in the care of patients. Radiologists specializing in breast imaging focus on mammography and diagnostic breast procedures. Our breast imaging radiologists also perform diagnostic procedures, including breast ultrasound, biopsies, MRI and MRI guided procedures as well as preoperative localization procedures. Our radiologists have extensive training and expertise in medical imaging, and specifically breast imaging, and provide the highest level of quality imaging services to all patients and healthcare providers as part of our collaborative multi-disciplinary team. They are also involved in research and training the next generation of radiologists.

Dr. Jon Hunter

Dr. Jon Hunter is the psychiatrist who focuses on the psychosocial care of patients undergoing diagnosis and treatment for cancer. As the Head of the Consultation-Liaison Program in the Department of Psychiatry at Mount Sinai Hospital, he also teaches undergraduate and post-graduate students and conducts research. The research topics include: minimizing chemotherapy side-effects via pre-emptive relaxation training, psychological support for women in high-risk families and the possible interactions between early life experience and coping with illness. In the oncology program Dr. Hunter sees people for diagnosis and treatment of coping-related issues and distress in cancer, often in collaboration with social work, nursing and oncology colleagues.

An oncology nurse is a nurse who has extra training in the provision of chemotherapy. He or she will administer your chemotherapy and supportive medications, conduct health histories and help you manage any treatment side effects.

Oncology social workers are specially trained to help support patients and their families through their cancer experiences. They help navigate practical supports such as finances and transportation, make referrals to community resources and offer emotional support and counselling.

Some types of genes greatly increase the risk of developing breast cancer. The genetic counsellor at the MKBC provides genetic counselling and genetic testing to people with significant family histories of breast cancer to see if they have one of these genes. If we find that a person is at greater risk of breast cancer we can offer him or her approaches to reduce the risk of developing the disease.

A dietitian can provide nutrition tips and strategies to patients having difficulty eating normally or who are losing weight as a result of their cancer or cancer treatments. Dietitians complete a full medical and nutritional history in order to provide nutrition education and recommendations tailored to patient’s individual needs.

Your treatment plan may include supportive care and/or cancer medications that are not funded by the Government or only partially covered by your private drug plan. A medication reimbursement specialist (MRS) can provide you with access to patient-support programs that can offer financial assistance, compassionate (free) drug or bridging drug supply while you wait for public or private coverage. The MRS also assists patients that do not have any drug coverage, providing information on the Trillium Drug Program and help with the application form. This support is available to help patients navigate the complex drug-support system that includes Government and private insurance and drug companies.

Oncology pharmacists verify and dispense your cancer related medications. The pharmacist will explain how your cancer medication works, its purpose and effects, the usual treatment schedule, how it is administered, what side effects to look out for and how to manage or prevent them. The pharmacist will also review your home medications and natural supplements, screen for drug interactions, and go over any dietary restrictions or medication precautions.

If you are First Nations, Inuit or Métis and screening for cancer or have cancer, our Indigenous Patient Navigator can help: answer your questions about what to expect with upcoming appointments or tests, introduce you to your health care providers, find more information about cancer and treatment, connect you with spiritual support, as well as support in the community and assist with applications for financial and transportation services.

You may ask your health care provider to make a referral.

The clerical team is essential in keeping the clinic organized – from preparing of a patient’s first visit to booking of follow up appointments.

They also work closely with our volunteers to help make sure the clinic day runs smoothly and that patients receive that extra special care and attention.
