WALES, July 1 — A 24-year-old woman who was raising funds for potentially life-saving cancer treatment abroad has died after a sudden brain bleed, her family has confirmed. Caitlin Leggett, who was battling acute myeloid leukaemia, passed away on June 15 at 2.42am, surrounded by her loved ones. She was 24.
Her twin sister Grace, brother Ethan, 27, sister Neve, 19, and parents Jennifer, 54, and Ian, 57, were at her bedside. “It was really hard,” Grace said.
“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.” The Leggett twins made headlines earlier this year after Caitlin’s diagnosis in April 2025 led to a remarkable discovery — the sisters, who had believed they were fraternal twins their whole lives, were actually identical. The finding came when Caitlin urgently needed a stem cell transplant to fight the cancer.
Following months of chemotherapy and a stem cell transplant in December 2025, Caitlin achieved complete remission. But in May 2026, doctors found the cancer had returned.
She was told that the treatment options available to her in the UK were unlikely to be curative, and that she had just six months to live on her current treatment plan. Caitlin and her family decided to pursue potentially curative treatment abroad, most likely in the United States, where treatment and associated costs could reach £500,000. They set up a GoFundMe fundraising page on June 2.
By June 10, Caitlin had raised £100,000 towards her treatment. On Saturday June 13, Caitlin experienced a sudden, serious brain bleed, followed by a series of strokes. Her health declined rapidly.
She died two days later. The family’s fundraising effort had drawn attention to the difficult choices facing patients when standard treatment options are no longer considered curative.
For now, the family has asked for privacy as they grieve. Consult your doctor for medical advice.
