Gillian Lightstone, aged 54, from Hemel Hempstead, was diagnosed with kidney cancer in September 2012. She had her right kidney removed at Charing Cross Hospital and started on a course of chemotherapy tablets. But, just six months later, and despite earlier clear CT scans and X-rays, she was devastated to learn the cancer had returned, and spread. She said: “It was completely awful. I had hoped to get another clear scan. I was feeling well and really thought it had gone. To then get the news that it had spread was terrifying. My husband and four children were distraught.”
