The Princess of Wales has made an “incredibly poignant” visit to the hospital where she was treated for cancer to personally thank staff for her care. Kate returned to the Royal Marsden Hospital in Chelsea, west London, on Tuesday morning, where she expressed her gratitude to her medical teams and showed support to patients undergoing cancer treatment. The surprise official solo engagement – the princess’s first of 2025 – was described as an important moment in Kate’s “personal journey”.
