Just two months after the King publicly shared his cancer diagnosis last year, Kate Middleton also revealed that she had been diagnosed with an unspecified form of cancer.

She stepped away from the public eye for several months but later announced in September that she was cancer-free following treatment.

Just last week, during a visit to Northern Ireland, Charles referenced Winston Churchill while sharing words of encouragement for others battling cancer.

“Keep buggering on,” he said. “You just have to push on, don’t you?”
