All selected studies evaluated p53 expression in non-proliferative lesions, which included lesions such as lactating adenoma, duct ectasia, hyperplasia without atypias, apocrine metaplasia, inflammation, fibrocystic disease, fibrosis, fibroadenoma, adenosis, apocrine adenosis and microglandular adenosis. Here, TP53 is linked to Fibroadenoma.
