multiple endocrine neoplasia (MEN)

An inherited condition that is associated with tumours in more than one endocrine gland and an increased risk of endocrine system cancers.

There are different types of multiple endocrine neoplasia, and each type is associated with different cancers. MEN1 increases the risk of tumours in the parathyroid, pituitary and adrenal gland as well as the pancreas and ovary. MEN2 increases the risk of tumours in the thyroid, adrenal gland and parathyroid gland.
