The document discusses different benign breast diseases categorized into several sections. Non-proliferative changes include cysts, apocrine metaplasia, fibrosis, calcification, and chronic inflammation. Intraductal proliferative lesions consist of usual ductal hyperplasia, atypical ductal hyperplasia, and atypical lobular hyperplasia. Fibroepithelial lesions contain fibroadenoma and phyllodes tumor. Adenosis and sclerosing lesions comprise sclerosing adenosis, microglandular adenosis, apocrine adenosis, and tubular adenosis. Papillary lesions involve intraductal papilloma. Nipple lesions consist of nipple adenoma, squamous
