Introduction Cancer biology dominates the behavior and prognosis of a tumor. A high-grade (grade III) tumor is seen as a higher risk for recurrence and having radiation therapy reduces this risk. For any given tumor size and breast cancer stage, prognosis is poorer when tumor grade is higher. New research is focusing on genetic factors such as the presence of the c-erbB-2 protein in predicting breast tumor aggressiveness and nodal metastasis . The more closely the tumor resembles normal tissue, the lower the tumor grade and the less aggressive it will behave.

Pathologists (physicians who conduct laboratory studies of tissues and cells) often assign a histologic grade to a patient’s cancerous breast tumor to identify the type of tumor present and help determine the patient’s prognosis (projected outcome). Patients whose cancers have ER or PR-positive receptors tend to have a better prognosis than patients whose cancers do not have these receptors. Nottingham evaluates the cancer cell structure and distribution to determine how aggressive the malignancy will be. The score is called a Bloom Richardson Grade (BR) and is expressed [sum of the grades]/9. It is done routinely on all invasive breast cancers.. So in estrogen receptor (ER)-positive breast cancer, the tumor grade, which is a histological measure, is often categorized as the Nottingham combined histologic grade, often referred to as the Elston-Ellis grade.
