Biopsy may reveal cancer in women with rare but benign breast condition

On a mammogram, LCIS and ALH typically look like small deposits of calcium.In women whose initial breast biopsies revealed certain rare, yet benign breast conditions, more extensive follow-up surgical biopsies found that up to 25% of them actually had cancer in addition to these benign lesions. Most of the cancers were invasive, meaning the tumors had penetrated normal breast tissue and would require treatment. In the study, conducted at the School of Medicine, the women’s initial biopsies had revealed atypical lobular hyperplasia (ALH) or lobular carcinoma-in-situ (LCIS), conditions that increase the risk of breast cancer, but which are themselves considered benign.
