Catherine, Princess of Wales, opened up about sneaking into a major U.K. hospital for secret cancer treatment and appeared moved by one patient's comment on the day she announced she was in remission.

In March, Kate confirmed she had been diagnosed with an unknown form of cancer. What followed was a nine-month battle as she underwent “preventative chemotherapy”. She endured intense online speculation in the weeks leading up to the public announcement and has largely stayed out of the spotlight since.

Kate Middleton, who first announced her cancer diagnosis in March 2024 and completed her treatment in September, revealed her cancer is now in remission.
