Collaborative Stage

Note 1: BR may also be called: modified Bloom-Richardson, Scarff-Bloom-Richardson, SBR grading, BR grading, Elston-Ellis modification of Bloom Richardson score, the Nottingham modification of Bloom Richardson score, Nottingham-Tenovus, or Nottingham grade.
Note 2: Code the tumor grade using the following priority order: a). Bloom-Richardson scores 3-9; b). Bloom Richardson grade (low, intermediate, high).
Note 3: BR score may be expressed as a range, 3-9. The score is based on three morphologic features of "invasive no-special-type" breast cancers (degree of tubule formation/histologic grade, mitotic activity, nuclear pleomorphism/nuclear grade of tumor cells). If a report describes any of the factors with words (low, intermediate, high) rather than numbers, do NOT attempt to translate these words into a score/number.
