Doctors in Ho Chi Minh City have successfully removed a giant tumor from the face of an 18-year-old girl after a nine-hour surgery Tuesday .
The operation was performed by renowned American plastic surgeon McKay McKinnon and doctors from the city's FV Hospital.
They removed a 500-gram tumor which had covered half of the face of Nguyen Hoang Thien An of Ba Ria-Vung Tau Province.
An was born normal developed a small tumor over her right eye when she turned seven months old.
The tumor grew rapidly, deforming her nose, lips, and eyes and gradually covering half her face.
But her family could not afford treatment until 2007, when she first underwent a surgery.
However, the tumor grew once again, she underwent another surgery the following year, and it returned yet again.
An received support from Vovicare, a charity run by ethnic Vietnamese living in Australia and Canada-based Virtual Medical Miracle Network, which connected her with McKinnon.
An's latest surgery was funded by the FV Hospital, while McKinnon performed the surgery for free.
The American doctor came to Vietnam last year to remove a 90-kilogram tumor from the leg of Nguyen Duy Hai, now 33, of Lam Dong Province, and operated on some others with unusual tumors.
