The Nottingham Score System, also referred to as the Breast Cancer Grading System, is a methodology employed to evaluate the differentiation level of breast cancer cells. This system hinges on the assessment of three principal tumor cell characteristics: cellular morphology, the count of mitotic figures, and nuclear pleomorphism. Utilizing these attributes, the grade of the tumor is ascertained, which aids in forecasting the tumor's growth velocity and metastatic potential.

Cellular morphology pertains to the cells' appearance and structure. In poorly differentiated tumors, the morphology tends to be markedly different from that of normal cells, manifesting as irregularities in cell size and shape. The count of mitotic figures denotes the frequency of observed cell divisions under microscopic examination. An elevated mitotic figure count typically signifies active tumor cell proliferation, suggesting rapid tumor growth. Nuclear pleomorphism, on the other hand, describes the variability in nuclear size, shape, and chromatin distribution. Highly pleomorphic nuclei are generally correlated with malignancy.

Tumors are classified into three grades based on these features: Grade 1 (low malignancy), Grade 2 (moderate malignancy), and Grade 3 (high malignancy). This grading system is pivotal for devising treatment strategies and estimating patient outcomes. For instance, tumors of lower grade may be more amenable to conservative treatment, whereas those of higher grade might necessitate more aggressive therapeutic interventions. Consequently, the Nottingham Score System is integral to the diagnosis and management of breast cancer.
