His Majesty has filmed a first-hand account regarding his journey with cancer, which will be broadcast as part of this year's annual cancer awareness initiative, spearheaded by medical research organisations and a major network.
Buckingham Palace stated the King would discuss his "path to recovery" as a person living with the disease, in a recorded address on Friday at the evening slot.
The message, recorded at Clarence House a fortnight ago, will stress the vital significance of cancer screening checks to help guarantee more people detect the illness at an initial point.
This constitutes a rare update on the medical condition of the King, who has been in a course of therapy since the news was shared in early last year. Analysts suggest improbable the King will identify his type of cancer.
The annual charity initiative each year raises funds for scientific studies and therapies and urges people to get screenings to boost the probability of an prompt identification.
The King's candid approach about his illness, and his experience as a patient, has been aimed to increase understanding and to persuade more people to get tested - and this will be escalated with this exceptional royal involvement.
Up until now the King's main approach to his cancer has been to keep working, maintaining a hectic timetable in spite of his regular rounds of therapy, and he seems not to have sought to be defined by his illness.
The past twelve months has seen the 77-year-old Monarch, undertaking several international tours, including to Italy and Canada, and hosting the biggest number of inward state visits to the UK for almost 40 years, which included the German president last week.
This Friday's awareness programme on the network, presented by well-known figures such as a team of famous hosts, will encourage people not to be frightened of getting cancer checks.
Each presenter have been affected by cancer - McCall said recently she had undergone surgery for the disease, while Clare Balding was treated for thyroid cancer over a decade ago. Host Adam Hills has previously spoken about his father, who had one form of cancer and then later another illness.
The broadcast will appeal to the roughly millions of people in the UK who health organisations says are not compliant with NHS screening schemes, with an online checker to let people see if they are able for screenings for key health indicators.
In an effort to explain health tests and demonstrate the benefit of early diagnosis there will be a direct feed from hospital departments at Addenbrooke's and Royal Papworth hospitals in Cambridge.
"My aim is to remove the anxiety out of preventative tests and prove everyone that they are not alone in this," commented a presenter.
At present in the UK, there are three national health screening services - for bowel, breast and cervical cancer - offered to eligible individuals.
A recently launched preventative initiative is also being gradually implemented for people at increased risk of being diagnosed with the disease, focusing on people in a specific age bracket, who are smokers or were former smokers.
Individuals may discuss prostate cancer checks, but there is lacking a standardised service operational.
The charity initiative, which has generated over one hundred million pounds since 2012, is funding multiple research studies with 13,000 patients.
The Monarch, in a address for guests at a gathering for support groups in earlier this year, had discussed recognising the "daunting and at times frightening reality" for those diagnosed and their families.
But he noted his personal journey of coping with cancer had demonstrated that "the most difficult times of illness can be illuminated by the support of carers," as he praised those who cared for individuals with the illness.
The Palace has not made public the specific type of cancer the King has, or what treatment he has received. The King's cancer was detected following he had had a medical treatment.
