World's Tallest Man Gets Radiation to Zap Growth

Aug. 19, 2010 — -- Sultan Kosen wants what many other 27-year-old men want in life -- to meet a wonderful woman, settle down and have a family.

But before he can focus on that, he's focusing on putting a stop to his increasing height.

He is more than eight feet tall and is considered by Guinness World Records to be the tallest living man.

Kosen suffers from gigantism, a rare condition caused by excessive secretion of growth hormone that results from a tumor on the pituitary gland.

"He has grown two inches in the last six months, so he's now eight-foot-four," said Dr. Jason Sheehan, an associate professor of neurosurgery at the University of Virginia.

Sheehan will perform a procedure on Kosen today that he says will stop him from growing any taller. The procedure, gamma knife radiosurgery, involves directing thin beams of radiation at Kosen's tumor.

"It inactivates the cells and they will slowly die, causing the tumor to shrink," said Sheehan. "The brain won't release any more growth hormone, and the hope is he'll stop growing."

Kosen and others with gigantism grow extremely tall and also have very large organs.

The radiation procedure can reverse Kosen's organ growth, Sheehan said. The bone growth, however, cannot be reversed.

"He will always remain tall," Sheehan said.

On the day before the procedure, Kosen said he felt fine, but was exhausted after traveling from his native Turkey.

Through his translator, Kelly Garrett of Guinness World Records, he joked about his unusual stature and talked about life as the world's tallest living man. Garrett has traveled with Kosen for several months as he made public appearances.

"He can see everyone from a long distance and can also easily change bulbs and curtains for his mother," said Garrett.

There are many disadvantages as well.

"He can't go to regular stores to buy clothes or shoes and he can't fit into normal cars," said Garrett. "He has to have everything specially made, which is expensive."

He also gets tired easily.

"He has to carry around about 150 kilos [about 330 pounds]," said Garrett. "He also gets a lot of muscle aches and walks with a cane. He dislocated his knee a couple of years ago."

Kosen no longer hides his height from the public, Garrett said. Since he went into the record book in September, he's basking in the limelight.

"He gets recognized a lot, and he realized that people are genuinely interested in how he's doing," Garrett said.
