a Subcategories of BC classified by histological subtypes. The analysis demonstrates that BC histological subtypes are associated (p < 0.001) with distinct patterns of breast cancer subcategories. b Correlation of BC subcategories and age at primary diagnosis. Univariate analysis shows that age at primary diagnosis is a significant parameter for classifying bone-only histological subtypes (p = 0.001). Independent Variable: age at primary diagnosis. Dependent Variable: histological subtypes
