Doctors removed a 10-kg tumour, that grew on the back of a 27-years old Chinese patient and looked like a rucksack. The tumor of Yang Xiao, from Xi'an started to grow about ten years ago.

The doctors warned the young man, that the surgery was risky but that without it the tumour would continue to grow, and Yang Xiao would not be able to walk.

In 2007 the young man was diagnosed fibromatosis. Then he was suggested a surgery but was warned about possible risks.

At the end of 2013 the young man went to the hospital again. By that time the tumour reached 30-45cm and it was 17cm thick. The surgeons warned him again about the possible risks.

The doctors also warned him: if not operated, the tumour will grow even faster. As a result, the young man's father gave his consent for surgery. The operation took place on 19th of February and lasted nine hours. According to Daily Mail, the young man is still in the hospital. And though the tumour is removed, it is possible, that it could grow again.
