Doctors have removed what is believed to be the world’s largest tumour from a man’s leg – after it grew to more than 17 stone.

Yang Jianbin, 37, from Shanxi Province, China was born with a dark birthmark on the right side of his lower back – and noticed it getting larger when he was nine.

By the time he was 12, it had increased to the size of a fist and he had surgery to remove it.

But despite medical intervention, it started to grow again and a recent hospital check in Beijing revealed that the tumour had increased to an enormous 110kg – more than 17 stone.

Chief surgeon Chen Minliang said Yang suffered from Neurofibromatosis, a genetic disorder that affects the normal growth and development of cell tissue.

Yang had said previously that the huge tumour was so big he could only lie down or sit on bed all day.

He was given two hospital beds to accommodate the 1.2m tumour, which made up two-thirds of his total body weight.

Removal surgery involved nine doctors and lasted 16 hours. During the procedure, the patient received 5,000ml of blood, which is more than the entire amount an adult’s body holds.

But he is said to be recovering well and is expected to be discharged from hospital in Beijing later this month.

An overpass in Brazil that was part of the World Cup infrastructure plan has collapsed onto vehicles below.

The overpass in Cup host city Belo Horizonte collapsed Thursday afternoon. Local news media quote firefighters on the scene as saying at least one person has died and another 10 are injured.

Live TV images showed what appeared to be a school bus and other vehicles trapped under the rubble.

It’s not immediately clear if people are trapped inside those vehicles.

Doctors who performed an x-ray on a woman who suffered a stomach ache for six months were shocked to discover a fountain pen lodged inside her.

Student Shing Fang, 20, went to a hospital in Taipei, the capital of Taiwan, after the persistent pain became so unbearable she could no longer eat.

When doctors carried out an endoscopy, by inserting a camera through her mouth and into her stomach, they were amazed to find a long thin object badly corroded by stomach acid..

After ordering an x-ray, there were shocked when they realised that the four-inch long object was a fountain pen that had been there for around half a year.

The doctors operated immediately and removed the pen.

They warned that if it had been there any longer, it could have led to peritonitis, or even death.

As to how the pen got there, the young woman said she had no memory at all of swallowing it.

However, she agreed that it might well have been ingested after drinking too much when celebrating good exam results.

You might think you’d love to escape this busy world and spend some time alone with your thoughts. But a new study of people who did that shows that many of them found it wasn’t very fun.

Some even started giving themselves electric shocks as the minutes ticked by, apparently out of boredom.

Overall, the study found that when people were left alone to think for six to 15 minutes, they rated the experience on average in about the middle of a 9-point scale of enjoyment. About half gave it a rating at the halfway mark or below.

The study was released Thursday by the journal Science.
