Breast Pathology Fellowship

The Breast Service reviews over 2000 consultation cases and 1000 core needle biopsies each year. Breast specimens from surgical procedures performed at BWH – 1300 per year – may also be reviewed at the request of the staff pathologist. In addition, the Breast Service evaluates immunohistochemical studies for estrogen and progesterone receptors and HER2/neu.
Fellows participate in two tumor board conferences each week and present the pathologic findings for the patients discussed. This is an excellent opportunity to learn how medical oncologists, radiation oncologists, and surgeons integrate pathologic information to guide the treatment of patients.

Radiologic-guided core needle biopsies are reviewed at a conference with radiologists and surgeons every other week. The imaging features of benign and malignant lesions on mammography, ultrasound, and MRI are presented and correlated with the pathologic findings.

There is a weekly multi-disciplinary didactic conference on breast cancer with topics ranging from basic science to treatment protocols.

Fellows are expected to participate in the teaching of medical students and residents and are encouraged to pursue a clinical research project. Training periods can be adjusted to the needs of Fellows, but typically consist of three-month block units.


Fellows must be eligible for a Massachusetts medical license and have completed at least two years of anatomic pathology training.

Breast Pathology Observerships 

Observerships on the Breast Pathology Service are offered to qualified pathologists and pathologists-in-training both from within the United States and from abroad. Visitors may come for up to two months and must be entirely self-funded. Visiting pathologists may join daily pathology sign outs around a multi-headed microscope benefitting from the case-related discussions between fellow and breast pathologists for the daily workload. They can attend all Breast Conferences and departmental teaching and research conferences, and may review the extensive slide teaching set available. They will not be able to review medical records nor act as ‘fellows in training’ providing diagnostic services for current cases, nor will they be invited to undertake research during their observership. There is no official training or syllabus covered during the observership, and no assessment of the observer’s competence in breast pathology at the end. An official letter stating the observer attended during specified dates can be provided. For information on how to apply for an Observership in Breast Pathology contact Jane Brock. Email:
