Lobular intraepithelial neoplasia

What is Lobular intraepithelial neoplasia?

Lobular intraepithelial neoplasia meaning A condition in which abnormal cells are found in the lobules (glands that make milk) of the breast. This condition rarely becomes cancer. However, having lobular intraepithelial neoplasia (LIN) in one breast increases the risk of breast cancer in either breast. Types of LIN include atypical lobular hyperplasia and lobular carcinoma in situ (LCIS).
