Doctors remove world's largest malignant tumour weighing FOUR STONE from woman, 54
The huge three stone 8.7lbs growth was taken out of the 54-year-old's womb during a four-hour operation at a hospital near the capital Buenos Aires.
The unnamed patient was discharged weighing just over 16 and a half stone - five stone 7lbs less than when she was admitted.
Medics say they believe the malignant tumour is the biggest ever removed in the world. Malignant tumours of this type usually weigh between 4lbs and 7lbs.
Lead surgeon Dr Oscar Lopez said: 'I've never seen anything like it in my 34 years of medical service.
'In medical literature a giant tumour is one that weighs more than 8.8lbs. But we've not found any references to a larger tumour.
'Its weight is comparable to that of a four-year-old boy's. In layman's terms, it was as if this woman had been pregnant with quintuplets.
