Mexican doctors say they have removed a 15kg benign tumour from the body of a two-year-old boy.
Jesus Gabriel was born with a benign tumour that grew to cover the right side of his body from his armpit to his hip, the Associated Press reports.
At the time of surgery on June 14, the tumour weighed more than Jesus, who weighed just 12kg.
Dr Gustavo Hernandez, director of paediatrics at La Raza Medical Centre in Mexico City, said it took surgeons about 10 hours to remove the lump.
Jesus, who is from the northern state of Durango, is reportedly recovering well after surgery.
Dr Hernandez said that the operation was the first time Mexican doctors have removed a tumour bigger than the person carrying it.
