Early life

Yao Defen was born to poor farmers in the town of Liuan in the Anhui

 province of Shucheng County. At birth she weighed 6.16 pounds. At the age of three years she was eating more than three times the amount of food that other three-year-old children were eating. When she was eleven years old she was about six feet, two inches tall. She was six feet nine inches tall by the age of fifteen years.

The story of this "woman giant" began to spread rapidly after she went to see a doctor at the age of fifteen years for an illness. After that, many companies attempted to train her to be a sports star. The plans were abandoned, however, because Defen was too weak. Because she is illiterate, since 1992 Yao Defen has been forced to earn a living by traveling with her father and performing.

Yao Defen's giant stature was caused by a large tumor in the pituitary gland of her brain, which was releasing too much growth hormone and caused excessive growth in her bones. Six years ago, a hospital in Guangzhou Province removed the tumor, and she stopped growing.

The tumor returned and she was treated in Shanghai in 2007, but was sent home for six months with the hope that medication would reduce her tumor enough to allow surgery. The second surgery was never performed due to lack of funds.

 agreed to help Yao. She was taken to a nearby city hospital, where imaging procedures revealed that a small portion of her tumor, thought to have been removed many years before, still remained, causing continuing problems including weakening vision as it pressed against her optic nerve. She returned home, then was admitted for a month under observation in the larger Shanghai Ruijin Hospital, and given dietary supplements. In that hospital, her growth hormone was greatly slowed down, although it is still a problem. Upon her return home to her mother and brother, she was able to walk with crutches, unassisted by others, and was given a six-month supply of medicines and supplements in hopes of improving her condition enough to undergo surgery.
