Princess Kate has missed an expected appearance at Royal Ascot, with Prince William attending the event without her.

Kate, the Princess of Wales, canceled plans to attend the Royal Ascot horse race as she continues her recovery from cancer.

Kate, who shares three young children with William, has made a gradual return to public engagements this year since announcing in January that she is in remission from cancer. Kate has not shared details of the type of cancer with which she was diagnosed, though she has shared she underwent chemotherapy treatment.
