A Chinese man is recovering after having what is thought to be the world’s largest tumour removed in Beijing.
Yang Jianbin was born with a dark birth mark on the right side of his lower back.

Before his tenth birthday the birthmark began to grow into a tumour, and within two years had enlarged into the size of a fist.
Yang, now 37, had surgery to remove the small tumour, but it quickly started to grow again.
He recently checked into hospital, by which time the enormous growth weighed a staggering 110kg (17 stone).
Doctors described it as ‘the biggest nerve tumour we ever saw’.
Yang, who suffers from Neurofibromatosis, can barely walk and has to ‘lie down or sit on bed all day long’.
The eventual operation to remove the tumour took 16 hours and involved nine doctors.
During the surgery, Yang was given more than 5,000ml of blood - which is more than the entire amount an adult’s body holds.
He is now said to be recovering and is expected to be allowed home later in July.
