Surgical Oncologist, Breast Care of Western New York

My practice at Breast Care of Western New York offers women of all ages comprehensive surgical breast care for both benign and malignant conditions, including high risk evaluation and screening. As the management of breast disease becomes increasingly nuanced, it is important that patients are cared for by physicians up to date with the latest recommendations and guidelines. It is also important to stress that breast cancer treatment is multidisciplinary in nature, and addressing that aspect of care early on with patients sets appropriate expectations during the course of their treatment, which most often involves more than surgery alone.
