Kate reveals she has cancer: Princess of Wales bravely announces she is battling disease - but reassures nation 'I am going to be okay' | 22 March 2024 | The Princess of Wales has announced tonight that she has been diagnosed with cancer aged 42 and is undergoing "preventative" chemotherapy. In a deeply personal, unprecedented and emotional video message, filmed at Windsor on Wednesday, Catherine revealed the news had come as a "huge shock" and that she and William "have been doing everything we can to process and manage this privately for the sake of our young family." Speaking from a bench surrounded by daffodils and spring blossom, the future queen said: "It has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be okay." Catherine's cancer was discovered only after she underwent major abdominal surgery at The London Clinic in January. Kensington Palace has said it will not be sharing details of what kind of cancer the princess has, or what stage of cancer it is and has asked people not to speculate.
