Middleton first shared her cancer diagnosis in March 2024, saying that she began treatment in late February and was undergoing what she called “preventative” chemotherapy. Middleton and the royal family have not announced what type of cancer or what stage she had.

Kate's announcement comes after a year in which she largely withdrew from her royal duties while undergoing treatment.

Kate, the Princess of Wales, is sharing both a personal message of hope and a personal photo in honor of World Cancer Day. Kate, who announced in January that she is in remission from cancer, shared a photo of herself Monday standing outside in nature with her arms stretched wide.
