Which of the following benign lesion of breast is associated with moderately increased risk of invasive breast carcinoma?

Atypical lobular hyperplasia refers to proliferation of lobular type cells within the acini of a lobule. It is a benign breast disease associated with 4-5 times increased risk of developing breast cancer. In this type the cellular proliferation is mild and the cells fill the acini but do not distend most of them.
