Overview
Classification
Classification of breast lumps based on epithelial hyperplasia[1]
- 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
