Summary

The tumour spectrum associated with multiple endocrine neoplasia type 1 (MEN1) has been known for many years. New data suggest that females with MEN1 may face an additional, hitherto unrecognized, risk of early-onset breast cancer. The menin protein is certainly known to have a role in regulating oestrogen receptor activity; but how robust are the data linking MEN1 to breast cancer? This article examines the published data from the viewpoint of a cancer geneticist and considers whether there really is a justifiable indication for enhanced breast surveillance in women with MEN1.
