During the message, the king also encouraged viewers to make use of a new national online Screening Checker. He explained that the tool helps people understand what screenings are available to them, answers common questions and guides them toward taking that first step. As the festive season approaches, he urged people to reflect and make a personal commitment to early cancer checks, reminding viewers that their own life or the life of someone they love could depend on it.

Following the broadcast, Buckingham Palace released a statement acknowledging the overwhelming response to the king’s message. A spokesperson said His Majesty was deeply moved by the positive reaction from both the public and those working in cancer care. The palace added that the king was particularly pleased that his words had helped highlight the importance and benefits of screening programmes.
The statement reiterated that King Charles has long believed that if sharing elements of his personal health journey could lead to public good, then doing so was both his pleasure and his duty. His thoughts, the palace said, remain firmly with everyone affected by cancer and those who care for them.
While the king has not disclosed the specific type of cancer he is being treated for, aides have previously explained that he chose transparency to reduce fear and stigma around medical checks. Despite undergoing regular treatment, King Charles has continued to carry out royal duties whenever possible, maintaining a busy schedule throughout the year.
His appearance formed part of Stand Up To Cancer’s flagship fundraising campaign, which aims to raise vital funds, support research and encourage people to seek early diagnosis.
