A prolactinoma is a prolactin-producing tumor of the pituitary gland. In others, menstrual periods may become irregular or stop completely, and infertility is common. Mechanisms that have been suggested to explain this possible action of prolactin include the increased synthesis and expression of prolactin receptors in malignant breast tissue and a prolactin-induced increase in DNA synthesis in breast cancer cells in vivo Development of newer antipsychotic drugs that do not increase serum prolactin level may be indicated. The following procedures are done in collaboration with departments of Radiation Oncology and Neurosurgery:. Pituitary Tumors Read more.
