King Charles III was diagnosed with cancer this year after treating an enlarged prostate. His daughter-in-law, Kate Middleton, completed chemotherapy in September.

King Charles III has used his Christmas message to hail the efforts of healthcare workers and all those who support others, before praising the medical staff who provided “strength, care and comfort” during his and the Princess of Wales’ cancer treatments.

The British monarch recorded his annual holiday address from the chapel of a former hospital, rather than from a palace.

King Charles III is expected to use his annual Christmas message to highlight health workers, at the end of a year in which both he and the Princess of Wales were diagnosed with cancer.

Prince William, the Prince of Wales and heir to the throne, called 2024 "brutal" and the "hardest year of my life." Both King Charles and Kate Middleton were diagnosed with cancer.

King Charles has strayed from royal tradition with his year’s Christmas speech. The monarch, 76, who opted to break tradition last year by writing the speech himself, has prerecorded his festive broadcast in a different location to that of previous years.

While Christmastime is full of traditions, King Charles has broke from royal protocol for one of his most anticipated duties. RadarOnline.com can reveal Charles opted to film the annual Christmas address at a former hospital chapel, marking the first time in 18 years the annual speech will not be recorded at a royal residence.

As Charles put it, “I am deeply grateful, too, to all those who have offered us their own kind words of sympathy and encouragement.”

King Charles thanked the medical staff who treated him and his daughter-in-law Kate for cancer this year in his Christmas Day message. He also addressed the summer riots in Britain.
