Lobular carcinoma in situ (LCIS) is known to be a risk factor for the development of invasive breast cancer. Debate continues as to whether LCIS is also a precursor lesion. We hypothesized that, if LCIS were a precursor, its presence in the lumpectomy specimen, particularly at the margin, could increase local recurrence (LR) after breast-conserving therapy (BCT).
