A woman suffering from a rare hormonal disorder stands 6-feet, 6-inches, weighs 476 pounds and is still growing, the Daily Mail reports.
Tanya Angus is believed to be one of the tallest and heaviest women on the planet and doctors say her condition cannot be stopped by medication.
Angus, who appeared on NBC's Today show in June, lives in Nevada and suffers from a condition known as acromegaly, also referred to as gigantism.
At 20-years-old, Angus stood 5-foot, 11-inches and weighed just 115 pounds, but her height and her weight soon started to spiral out of control.
Her doctor diagnosed her with gigantism and she was sent to a specialist, the Daily Mail reported.
An MRI scan showed she had a tumor the size of a grapefruit in her brain which had wrapped itself around her inner carotid artery, causing an overproduction of growth hormones. In 2003, she underwent surgery to remove most of the tumor, although small parts of it were too difficult to separate from her brain.
She was then given a cocktail of drugs to try to control the huge amounts of growth hormones still in her body. Her growth hormones totaled 3,000. An average person has about 250.
Despite the drugs, her growth hormone level has never fallen below 900.
