A 24-year-old woman from Cardiff died on June 15, 2026, weeks after launching an online appeal that raised over £100,000 for leukaemia treatment.
Caitlin Leggett was diagnosed with acute myeloid leukaemia in April 2025. The diagnosis revealed that she and her sister Grace were identical twins, not fraternal as previously thought.

Grace's near-identical DNA made her ineligible to be a stem cell donor, complicating Caitlin's treatment.
After months of chemotherapy and a transplant in December 2025, Caitlin achieved complete remission.
However, doctors discovered the cancer had returned in May 2026 and gave her six months to live.
The family launched a GoFundMe on June 2, 2026, to pursue curative treatment abroad.
Caitlin suffered a sudden brain bleed and multiple strokes on June 13, 2026, and died peacefully two days later surrounded by family.
"We're only 24 – nobody expects this to happen... Being twins as well, you're not supposed to have one twin not be there," Grace said.
Grace quit her job as a complex care personal assistant in Bristol to move back to Cardiff to support her sister.
"It was really hard," she said.
The siblings spent their final days together, even trying on bridesmaids' dresses for their father's upcoming wedding the morning before Caitlin was admitted to hospital for the last time.
"We all got the chance to speak to her.
Neve put her favourite pillow spray on, we massaged her hands with lotion, and the nurses gave us a memory box with special paper and a charcoal wipe, so we could take her footprints and hand prints," Grace said.
