Record breaker: World's tallest woman Siddiqa Parveen. The world's tallest woman has been saved from being paralysed and going blind after doctors removed a huge tumour from her brain. Siddiqa Parveen, who is estimated to be 7ft 8in tall, had a spine on the 'verge of breaking' and was feared to be losing her sight. The 28-year-old suffered from gigantism brought on by a tumour on the pituitary gland, producing excess growth hormone.
