The PNA is an international non-profit organization for patients with pituitary tumors and disorders, their families, loved ones, and the physicians and health care providers who treat them. PNA was founded in 1992 by a group of acromegalic patients in order to communicate and share their experiences and concerns. PNA has rapidly grown to become the world's largest and fastest growing patient advocacy organization devoted to the treatment and cure of pituitary disorders. PNA is supported by an international network of the world's finest physicians and surgeons. Our goal is to reach every patient who may be forgotten, abandoned, or worse yet, undiagnosed after many years of suffering. We are doing this in three ways: (1) by providing public awareness programs and educational seminars, (2) by assisting the medical community in developing uniform standards for early diagnosis, surgery, radiation, pharmacological treatment and follow-up, and (3) by having interactive web sites and a referral program on these web sites.
