King Charles III said Friday that his cancer treatment will be reduced in the new year because of early diagnosis, effective intervention and adherence to doctors' orders.

Charles, 77, revealed the information in a recorded message broadcast on British television Friday as part of a campaign to encourage people to take advantage of screening that can detect cancer in its early stages when it is easiest to treat.

Buckingham Palace made the announcement last year that doctors had detected cancer in the king.

"Early diagnosis quite simply saves lives," the king said Friday.

"I know, too, what a difference it has made in my own case, enabling me to continue leading a full and active life even while undergoing treatment," he added.
