A surgical team in India successfully removed a brain tumor from a man that weighed over four pounds.
The tumor was as big as the man's head.
The neurosurgeons believe it's the largest brain tumor successfully removed from a human.
The tumor was taken from a 31 year-old man in a complex seven hour-long operation February 14th.
The lead surgeon said managing the blood loss from the patient was a major challenge.
He said the tumor sat like a head on top of the patient's head making it very difficult to operate without damaging nerves.
The patient is a small shopkeeper in northern India.
He and his wife are struggling to pay for his treatment and have borrowed money from their relatives and friends.
