King Charles has filmed a personal message about his journey with cancer, scheduled for transmission as part of this year's Stand Up To Cancer campaign, organised by medical research organisations and a major network.
Buckingham Palace confirmed the King would reflect on his "healing process" as a cancer patient, in a video message on Friday at the evening slot.
The message, taped inside a royal residence two weeks ago, will emphasise the importance of routine screenings to increase the likelihood more people diagnose the illness at an initial point.
This constitutes a infrequent public commentary on the medical condition of the Monarch, who has been in a course of therapy since his condition was announced in the start of 2024. However, it is believed improbable the King will identify his type of cancer.
The awareness event each year generates donations for scientific studies and patient care and prompts people to get check-ups to boost the odds of an early diagnosis.
The King's public discussion about his condition, and managing the disease, has been designed to raise awareness and to encourage more people to get screened - and this will be taken a step further with this unusual royal involvement.
To date the King's main approach to his cancer has been to maintain his duties, preserving a busy schedule alongside his regular rounds of care, and he appears not to have desired to be defined by his illness.
Recently has seen the Sovereign, undertaking several foreign visits, notably to Italy and Canada, and welcoming the highest tally of official guests to the UK for a generation, which included the German president recently.
The upcoming Stand Up to Cancer show on Channel 4, featuring well-known figures such as Davina McCall, Adam Hills and Clare Balding, will appeal to people not to be scared of getting health screenings.
All three have been had experience with cancer - Davina McCall disclosed last month she had undergone surgery for a tumour, while another presenter was treated for a thyroid condition more than 15 years ago. Presenter Hills has previously discussed his father, who had stomach cancer and then later leukaemia.
The broadcast will reach out to the approximate nine million people in the UK who Cancer Research UK estimate are not current with public health checks, with an online checker to let people determine if they are able for screenings for breast, bowel and cervical cancer.
In an attempt to explain health tests and illustrate the value of early diagnosis there will be a real-time transmission from hospital departments at two Cambridge hospitals in Cambridge.
"The goal is to remove the anxiety out of preventative tests and prove the public that they are not isolated in this," said Davina McCall.
At present in the UK, there are several key NHS cancer screening programmes - for bowel, breast and cervical cancer - offered to specific demographics.
A new lung cancer screening programme is also being phased in for individuals at high risk of developing the disease, primarily aimed at people of a certain age, who are smokers or used to.
Male patients may discuss specific tests, but there is not a universal scheme operational.
The fundraising campaign, which has generated £113m for many years, is financing multiple research studies involving 13,000 patients.
His Majesty, in a message for dignitaries at a event for related organisations in the spring, had discussed acknowledging the "intimidating and at times frightening situation" for those diagnosed and their families.
But he noted his first-hand encounter of living with cancer had demonstrated that "periods of great challenge of sickness can be illuminated by the support of carers," as he thanked those who cared for cancer patients.
Royal representatives has not made public the specific type of cancer the King has, or what treatment he has received. The King's cancer was detected after he had had a routine operation.
