The role of Medical Oncology in breast cancer management includes supervision and administration of chemotherapy and or hormone therapy before or after breast cancer surgery and the management of patients whose breast cancer has spread.

The service is provided at the Dunmanway Day Unit at Cork University Hospital.

The Medical Oncology consultants also provide care at Kerry General Hospital, Tralee and at the Mercy University and South Infirmary Victoria University Hospitals.

The Dunmanway Day Unit is located above the Radiotherapy Unit which allows for close collaboration between services. The service is also integrated with the Oncology Clinical Trials unit at CUH. This Health Research Board funded unit provides access to national and international studies for patients with breast cancer.
