Following the broadcast, a Buckingham Palace spokesperson said the king had been delighted by the sensitivity and scale of the global response. The spokesperson added that His Majesty believes sharing aspects of his diagnosis and treatment journey can serve a greater public good, particularly by highlighting the importance of screening programmes.

While the king has not disclosed the specific type of cancer he is being treated for, palace aides have previously explained that he chose to go public with his diagnosis to reduce fear and stigma and encourage others to seek medical advice early. Despite ongoing treatment, King Charles has continued to carry out royal duties where possible and has maintained a demanding public schedule throughout the year.

Friday’s appearance formed part of Stand Up To Cancer’s flagship fundraising event, which aims to support research, raise awareness and help people understand that early detection can save lives.
