On December 12, King Charles shared a positive update about his cancer treatment, and encouraged everyone to attend invaluable cancer screenings. According to a royal expert, the monarch had a rather "un-regal" reaction to learning he had cancer. Meanwhile, The King continues to hold certain details regarding his health close to his chest.

"Good news by sticking to doctor's orders" is the Daily Express's take, quoting the King - who said his "early diagnosis, effective intervention, and adherence to doctor's orders" means his scheduled treatment can be reduced next year.

King Charles III will deliver a rare cancer address on Friday at 8pm, recorded at Clarence House, describing his diagnosis as 'daunting and frightening' while urging early screening.
