Pathologists have an important role in medicine, and nowhere is this more evident than in the care of breast cancer patients.

Clinical Care

In clinical care, only pathologists make the diagnosis of breast cancer. We determine whether a tumor is benign or malignant, as well as how far the tumor has grown within the breast and whether it has spread to lymph nodes or other organs. We also determine kinds of proteins the tumor expresses, such as ER and HER-2, and our analysis determines whether or not the tumor should be treated with endocrine therapy (like tamoxifen, among others) or anti-HER-2 therapy (like trastuzumab, among others).

Oncologists and surgeons read our diagnoses and analysis to patients, and they generally treat patients based upon standardized protocols for these diagnoses. We are also always available to discuss our findings with the patient directly.

Our research has direct impact on patient care, for instance by identifying new targets for therapy and new tools for making accurate diagnoses. Pathologists study actual human cancers; we study the tumors and tissues that come directly from patients, not from mice (which are not always the same as human tumors) or cell lines artificially grown in culture.
