The cause of pituitary tumors remains unknown. It has been shown that stress can significantly raise prolactin levels, which should make stress a diagnostic differential, though it usually is not considered such. Most pituitary tumors are sporadic — they are not genetically passed from parents to offspring. The majority of moderately raised prolactin levels (up to 5000 mIU/L) are not due to microprolactinomas but other causes. The effects of some prescription drugs are the most common. Other causes are other pituitary tumours and normal pregnancy and breastfeeding. This is discussed more under hyperprolactinaemia. The xenoestrogenic chemical Bisphenol-A has been shown to lead to hyperprolactinaemia and growth of prolactin-producing pituitary cells. The increasing and prolonged exposure of Bisphenol-A from childhood on, may contribute to the growth of a<unk> .
