Overview
- Caitlin Leggett, 24, died on 15 June after a sudden brain bleed followed by multiple strokes that caused a rapid decline, her family said.
- She was diagnosed with acute myeloid leukaemia in April 2025, achieved remission after chemotherapy and a stem‑cell transplant in December 2025, and relapsed in May 2026 when doctors said UK treatments were unlikely to be curative.
- Her identical twin, Grace, launched a GoFundMe to raise about £500,000 for specialist treatment overseas and had raised more than £120,000 while pausing her job to care for Caitlin.
- The family said the options being explored included specialist centres in the United States or CAR‑T cell therapy in China or Singapore, treatments that can cost hundreds of thousands of pounds and are not routinely available on the NHS.
- The family will share funeral details and the fundraiser's future in due course, and the case highlights how families increasingly turn to public appeals to seek costly overseas care when UK options are limited.
