The world’s tallest man—who stands at a height of more than eight feet, according to the Guinness Book—will undergo radiosurgery to try to correct the condition responsible for his height. Sultan Kösen, 27, has acromegaly—caused by a benign tumor in his pituitary gland, which releases an excess of growth hormone.
Kösen has undergone multiple operations and therapy sessions in Turkey. In May, UVA professor of medicine and neurosurgery Dr. Mary Lee Vance changed Kösen’s medical therapy to a new drug and discouraged another operation because his tumor was deemed inoperable.
On Wednesday, Kosen will undergo Gamma knife surgery at the hands of Dr. Jason Sheehan. The surgery, together with the new medication, may control the disease, and according to a press release from UVA, a cure will eventually be found.
