Oksana Masters was born two years after Chernobyl with several radiation-induced birth defects. This included tibial hemimelia (resulting in different leg lengths), missing weight-bearing shinbones in her calves, webbed fingers with no thumbs, and six toes on each foot.

She was abandoned by her birth parents at a Ukrainian orphanage where she lived until age 7 when she was adopted . Since then Oksana has won eight Paralympic medals including two golds.

She tells Ed Harry her story.
