The huge growth was taken out of the 54-year-old’s womb during a four-hour operation at a hospital near Buenos Aires in Argentina.
Surgeons believe the malignant tumour is one of the biggest ever removed in the world. Malignant tumours of this type usually weigh between two and three kg, reports the Daily Mail.
Lead surgeon Oscar Lopez said: “I’ve never seen anything like it in my 34 years of medical service. A giant tumour is one that weighs more than 4.3 kg.
He added, “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.”
The woman had trouble performing everyday tasks like walking and bending down to tie her show lace.
