King Charles III announced Friday that his cancer treatment schedule will be scaled back in the new year, crediting an early diagnosis and using the occasion to urge the public to prioritize cancer screening.

In a pre-recorded video message released as part of Channel 4 and Cancer Research UK’s Stand Up To Cancer broadcast, the monarch said early detection and treatment had played a crucial role in his ability to maintain an active life while undergoing care.

“Thanks to early diagnosis and treatment, my own schedule of cancer treatment can be reduced in the New Year,” the king said, adding that the early intervention had allowed him to continue fulfilling his duties.

The message aired ahead of a live broadcast from a cancer clinic at Addenbrooke’s Hospital in Cambridge, hosted by Davina McCall.

Speaking during the festive season, Charles asked viewers to reflect on those affected by the disease across the United Kingdom.

“This is a season when our thoughts turn to celebrations with our friends and families,” he said. “In the midst of this festive period, I wanted to ask you to join me in holding a special place in your hearts, minds and prayers for the hundreds of thousands of people who receive a cancer diagnosis each year — and for the millions more who love and care for them.”

The king described a cancer diagnosis as an overwhelming experience, drawing on his own journey, and emphasized that early detection can dramatically change outcomes.

“Early diagnosis is the key that can transform treatment journeys,” he said, noting it gives medical teams vital time and offers patients “the precious gift of hope.”

Charles also paid tribute to what he called the “community of care” surrounding cancer patients, including doctors, nurses, researchers and volunteers. At the same time, he expressed concern that millions are missing opportunities for early diagnosis.

“At least 9 million people in our country are not up to date with the cancer screenings available to them,” he said. “That is at least 9 million chances for early diagnosis being missed.”
