Overview
Classification
Classification of breast lumps based on epithelial hyperplasia[1]
- Approximately 65% of all benign breast disease 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 atypia with 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
Classification of benign breast lesion regarding to histological region:[2]
- Terminal and lobular ducts
- Acinar distention
- Cyst
- Intralobular connective tissue proliferation
- Sclerosing adenosis
- Fibroadenoma
- Phyllodes tumor
- Hamartoma
- Epithelial changes in terminal duct lobaular units (TDLU)
- Apocrine metaplasia
- Ductal and lobular hyperplasia, usual and typical
- Papillomatosis
- Intracystic papilloma
- Acinar distention
- Ductal system
- Ductal ectasia
- Intraductal papilloma
- Lesion of different origin
- Fatty tissue lesion
- Lipoma
- Liponecrosis
- Fibrous tissue lesions
- Focal fibrosis
- Diabetic mastopathy
- Pseudoangiomatous stromal hyperplasia (PASH)
- Myofibroblastoma
- Vascular origin
- Hemangioma
- Inflammatory origin
- Mastitis/abscess
- Tuberclosis and sarcoidosis
- Foreign body granuloma and siliconoma
- Lymph node origin
- Inflammatory lymoh nodes
- Fatty tissue lesion
Risk factors
Associated risk factors leading to female breast cancer:
- Age: probability of breast cancer from birth to 39 years; 1 in 202, from 40 to 59 years; 1 in 26, from 60 to 69 years; 1 in 28.
- Personal history of breast cancer
