The Monarch has recorded a intimate address concerning his journey with cancer, set to air as part of this year's annual cancer awareness initiative, spearheaded by Cancer Research UK and Channel 4.
The royal household stated the King would discuss his "path to recovery" as a person living with the disease, in a video message on this Friday at the evening slot.
The recording, filmed within a royal residence recently, will emphasise the vital significance of cancer screening checks to help guarantee more people detect the illness at an early stage.
This constitutes a uncommon insight on the health of the King, who has been in a course of therapy since revealing his diagnosis in early last year. However, it is believed doubtful the King will identify his type of cancer.
The awareness initiative each year generates donations for medical research and patient care and prompts people to get health assessments to boost the chances of an timely detection.
The King's candid approach about his condition, and living with cancer, has been intended to promote education and to persuade more people to get checked - and this will be advanced with this unusual personal contribution.
Up until now the King's main approach to his cancer has been to continue his schedule, maintaining a busy schedule in spite of his regular rounds of care, and he appears not to have desired to be characterised by his condition.
Recently has seen the 77-year-old Monarch, embarking on several international tours, such as visits to Italy and Canada, and welcoming the biggest number of foreign dignitaries to the UK for almost 40 years, featuring the German president last week.
Friday evening's Stand Up to Cancer programme on the network, presented by celebrities including Davina McCall, Adam Hills and Clare Balding, will encourage people not to be afraid of getting cancer checks.
The hosts have been had experience with cancer - Davina McCall said last month she had had an operation for breast cancer, while Clare Balding was treated for the illness more than 15 years ago. Presenter Hills has previously mentioned his parent, who had a diagnosis and then later another illness.
The programme will target the roughly 9m people in the UK who health organisations state are not compliant with public health checks, with an website to let people determine if they are able for screenings for key health indicators.
In an attempt to explain cancer checks and illustrate the value of timely identification there will be a direct feed from cancer clinics at medical facilities in Cambridge.
"I want to remove the anxiety from cancer screening and demonstrate all people that they are not on their own in this," stated Davina McCall.
At present in the UK, there are several key NHS cancer screening programmes - for specific cancers - accessible for eligible individuals.
A recently launched lung cancer screening programme is also being gradually implemented for anyone at potential risk of developing the illness, primarily aimed at people in a specific age bracket, who have a smoking history or were former smokers.
Individuals may request prostate screenings, but there is no national programme in place.
The charity project, which has raised £113m over the past decade, is financing dozens of medical projects encompassing thousands of patients.
His Majesty, in a statement for guests at a gathering for related organisations in the spring, had discussed acknowledging the "daunting and at times scary experience" for patients and their loved ones.
But he noted his experience of coping with cancer had demonstrated that "the most difficult times of disease can be illuminated by the support of carers," as he praised 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 undergone. The King's cancer was discovered following he had received a medical treatment.
