Cardinal Vincent Nichols said he saluted “the courage of the Princess of Wales in speaking so openly about her personal health.” In a video message released on Friday, Princess Kate, 42, thanked well-wishers for support during her protracted hospital stay and then announced: “The surgery was successful. However, tests after the operation found cancer had been present. My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment.”
