Breast Pathology

Breast cancer is the most common type of cancer affecting women worldwide. In the United States alone, over 200,000 new cases of breast cancer are diagnosed each year. Effective treatment can save many lives.

Developing a personalized treatment plan is a team effort, with many different specialists working together to provide the best possible care for each patient. The pathologist’s role is to determine the correct diagnosis by examining biopsy slides provided by either a referring physician or the patient. This diagnosis is then shared with oncologists and surgeons, who will work with patients to devise an appropriate treatment plan. But it all hinges on an accurate initial diagnosis. That’s why we’re here.
