A woman has had a five stone cyst removed after it began crushing her lungs put her at risk of heart failure.
The cyst, which weighed the same as ten newborn babies, is thought to be the biggest cyst in the world removed in one-piece.
This 24-year-old woman, from Mexico, who did not want to be named, noticed she had put on more than four stone and, despite dieting, she could no shift the weight.
Last year Dr. Erik Hanson Viana, 27, at the Mexico General Hospital, performed pioneering surgery to remove the cyst.
Now, more than six months on, the woman can walk again and lives a normal life.
Dr. Erik Hanson Viana removed the cyst, which weighted five stone, in a life-saving operation.
Dr. Hanson, from Mexico City, said: “This is the biggest cyst I have operated on, it was so large that it took up 95per cent of the patient’s abdomen.
“It’s really rare to operate on a cyst this big, it measured half a metre in diameter and the circumference was 157cm.
