Three members of the Windsor family have announced that they are suffering from cancer. Kate Middleton, the wife of his eldest son William, publicly revealed Friday evening that she too had cancer.

On January 21, the ex-wife of Prince Andrew, the king's brother, announced that she was suffering from malignant melanoma, a skin cancer. Six months earlier, in June 2023, she had already announced she had been diagnosed with an early form of breast cancer. The king has since canceled all official public engagements.
