Kate Middleton visited the Royal Marsden Hospital in London for her first appearance of 2025 on Jan. 14, and following her appearance, she took to Instagram to make a major announcement regarding her cancer battle. Posting on the Prince and Princess of Wales's joint account, the royal—who celebrated her 43rd birthday on Jan. 9—declared she was in remission from cancer.
"I wanted to take the opportunity to say thank you to The Royal Marsden for looking after me so well during the past year," the Princess of Wales penned. "My heartfelt thanks goes to all those who have quietly walked alongside William and me as we have navigated everything."
