ThiYang Jianbin, who is in his 30's, has been given two hospital beds to accommodate his giant tumour, which currently makes up nearly two-thirds of his total body weight.
"We weighed him a few days ago and he was around 150 kilogrammes," Yang's father said.
Yang suffers from a genetic disorder called neurofibromatosis that affects the normal growth and development of cell tissue, 'Global Times' reported.
Yang first discovered the tumour while he was a primary school student, but family members apparently ignored the condition until it began to grow.
The tumour has grown rapidly over the past two years, and has begun to hinder Yang's movement.
The surgery to remove the giant tumour may cost about 500,000 yuan (USD 80,500), the report said.
