Kensington Palace has confirmed that Catherine, Princess of Wales, will attend a reception with King Charles and Queen Camilla at St James's Palace to commemorate 125 years of Cancer Research UK. The event, which highlights the charity's contributions to cancer research and treatment, will also feature the Duke and Duchess of Gloucester. As Patron of the charity, King Charles will preside over the gathering, which aims to spotlight the work of researchers, clinicians, and volunteers in cancer prevention and treatment. Catherine, who was diagnosed with cancer in early 2024 and underwent six months of chemotherapy, announced her remission in January 2025 and has since resumed her royal duties. The reception will include immersive installations showcasing the charity's achievements and future innovations. Notably, Cancer Research UK has played a vital role in advancing cancer treatment, contributing to a doubling of survival rates in the UK over the last 50 years, with 80% of patients receiving drugs developed in collaboration with the charity.
