Shams Ul haq Qari / Barcroft India. Surgery: Khalida Akhtar, here with Dr Malik Azad, arrived at the hospital complaining of discomfort and a severe abdominal pain. Doctors claim to have removed the world's biggest cyst - weighing a massive 3.46st. The giant cyst, which weighed more than a five-year-old child, was removed from an 18-year-old patient. Surgeons removed the growth from Khalida Akhtar's ovary after she arrived at the hospital in Kashmir, a disputed region between India and Pakistan, complaining of discomfort and a severe abdominal pain.
