Overview
Classification
Classification of breast lumps based on epithelial hyperplasia
- Approximately 65% of all BBD considered as nonproliferative(NP)with relative cancer risk of 1.2, 1.4 times:
- Simple cyst
- Fibrosis
*** Fibroadenoma (simple)
**** Columnar alteration (Simple)
***** Apocrine metaplasia (simple)
****** Mild ductal hyperplasia
** Approximately 30% of total are classifed as [[proliferative disease(PD) with relative cancer risk of 1.7, 2.1 times
** Usual ductal hyperplasia
*** Sclerosing adenosis
**** Columnar hyperplasia
***** papilloma
****** Radical scar
*** Approximately 5% to 8% of the rest regarded to PD with atypiawith relative cancer risk more than 4 times
*** Atypical lobar hyperplasia
**** Lobular carcinoma in situ
***** Atypical ductal hyperplasia
**** Unclear risk
**** Mucocele like tumor
***** Apocrine atypia
****** Secretory atypia
