Doctors in India who have removed a 1.8kg (3.9lb) brain tumour from a 31-year-old man say it could be the largest in the world, reports BBC. The surgery, which lasted seven hours, took place on 14 February at the Nair hospital in the western city of Mumbai.

But the procedure was not made public as doctors were not sure until now if it had been successful.

"Now it's a matter of recovery but he's out of danger", Dr Trimurti Nadkarni, chief of neurosurgery, told the BBC.

Santlal Pal, a shopkeeper from the northern state of Uttar Pradesh, had been living with the tumour for three years before his surgery was carried out.
