ABSTRACT
There is a similar group of lesions collectively called lobular neoplasia (4,5), which are considered to be a type of in situ disease but are most likely a risk factor for cancer rather than a precursor lesion. Frequently found on core biopsy for investigation of benign calcifi cations, they are managed currently by initial surgical excision due to concerns about potential undersampling and the risk of an adjacent cancer being missed by initial needle biopsy. However, this is a controversial and developing area and further study of lobular neoplasia needs to be done.
