The world's tallest man has stopped growing after doctors at the University of Virginia Medical Center in the United States performed radiosurgery on him.

Sultan Kosen from Turkey is the world's tallest living man measuring 8-feet-3 inches. Kosen visited the University of Virginia Medical Center (UVA) in May 2010, to get treated for acromegaly, caused by a tumor in the pituitary gland. Sultan Kosen started growing at the age of 10 due to a tumor that caused more growth hormones to be produced from the pituitary gland.

Endocrinologist Mary Lee Vance from UVA placed Kosen on a new medication to stop the production of growth hormone. UVA neurosurgeon Jason Sheehan, MD, then performed Gamma Knife radiosurgery - a procedure to treat tumors using radiation - in August 2010, reported the ScienceDaily.

He said Kosen's doctors in Turkey told him that Kosen had stopped growing.

"The treatments that we provided at the University of Virginia have stopped the production of his excess growth hormone and stopped the growth of the tumor itself," ScienceDaily quoted Dr Sheehan as saying.

"I'm most pleased that we were able to help Sultan," Dr Sheehan said. "If he had continued to grow, it would have been life-threatening," he added.

Sultan Kosen has been listed as the world's tallest man in the 2010, 2011 and 2012 editions of the Guinness Book of World Records.
