Twin sisters race for overseas AML cure after relapse in Cardiff
Cardiff 24-year-old Caitlin Leggett’s AML has returned after remission and a stem cell transplant, and UK options are unlikely to be curative. She and her identical twin Grace, who cannot donate due to their near-identical DNA, are raising about £500,000 for potentially curative treatment abroad (US or CAR-T therapy) while continuing monitoring and trials. The twins only discovered they were identical after Caitlin’s diagnosis, and their fundraising aims to cover treatment and travel costs so they can face the future together.
