Pippa Boardman said she received a phone call at home from a man she vaguely knew through sport who worked at the hospital. "This man said to me 'Pippa, I don't want you to worry, but you've got cancer'," she told the BBC. Two days later, her consultant confirmed she had breast cancer.
Nine months on, Boardman, who is now recovering well, said the experience had caused lasting harm. "I lost my dignity and I've lost my privacy," she said. She also criticised the hospital trust's handling of her complaint, saying it took a lot of courage to report the breach and that the trust only apologised after the BBC contacted it.
Boardman said the trust told her it could not give her information about the employee because of his rights. "I kept thinking where are my rights in this," she said.
The Royal Cornwall Hospitals NHS Trust said it was "truly sorry" and that "appropriate action had been taken" following an immediate investigation. It added: "Whilst the member of staff had legitimate access to her records as part of their work, it was outside of their role to contact her. This should not have happened and we recognise the distress and concern it will have caused."
The trust said it had reminded staff that records "must only ever be accessed for a legitimate work-related reason" and was reviewing its policies in light of strengthened NHS England guidance on inappropriate access to patient information.
The case comes after other recent NHS data breaches, which Health Secretary Yvette Cooper described as a disgrace.
