Huang Chuncai receives treatment in his ward after the largest of Huang's tumours, which weighed 15kg (33lbs), was removed last month in a risky operation at a hospital in Guangzhou, southern China's Guangdong province, August 22, 2007. Huang, a 31-year-old native from a remote village in China's southern province of Hunan, says he is relieved after a part of his facial tumours, which originally weighed about 23kg, was removed. Yet doctors say the surgery has caused him to lose his balance. The disease, called Neurofibromatosis, is a genetic disorder of the nervous system that primarily affects the development and growth of neural cell tissues, according to the U.S. National Institutes of Health.
