public for revealing he had undergone a prostate procedure – as well as the significant awareness it raised – encouraged the King to reveal his cancer diagnosis in the hope the same would happen.

Charles had his first public outing after his diagnosis was revealed at a cancer hospital on April 30, where he met with fellow patients.

His aides took the opportunity to point out that not all recovery programmes for cancer patients are the same.

It has been widely noted that he has not suffered any hair loss from his treatment, which was said to have been a natural concern for the King.

Thankfully, he has also not experience any debilitating side effects from the treatment, details of which have not been disclosed.

A source told The Sun of his treatment that it is ‘not pioneering in any way as it’s available for any cancer patient.’

‘The treatments are highly evolved and sophisticated in ways previous treatments were not,’ they added.

The treatment did however prevent him from appearing at the Trooping the Colour in June on his horse Noble, who was instead ridden by Princess Anne for the King’s birthday celebration.

Claims at the time that the monarch had been left ‘furious’ by the decision are now believed to have been downplayed by the Palace.

He reportedly ‘accepted the reality of the situation’, understanding that even if it weren’t for the cancer, his prostate procedure would have stopped him riding anyway.

Rather than his ill health stopping him from carrying out his public duties, it has been claimed the decision to postpone his public facing role was made as a ‘precautionary measure’ because of the King’s diminished immune response to other diseases.

During his 103 days away from public duties, Covid-style tiers were in place and he was restricted to the amount of people he could be with.

He was planned to have weekly treatment in London and factor in vital periods of rest time at Sandringham, Highgrove and Windsor.

This was reportedly thrown into chaos early on in his treatment when his son, Prince Harry, announced he would fly in from Los Angeles to see his father.

The King delayed his helicopter flight to Sandringham, and Harry was given just 30 minutes of his company at Clarence House, due to plans which were put in place to avoid the King contacting a secondary infection.

As the warmer months approached they felt confident to relax the Covid-style tiers, allowing him to take part in crucial events such as the D-Day commemorations.

One source explained: ‘Rest and recovery has to be taken as seriously a priority as duty, public duty, so we build in rest periods and try to limit the number of hours a day that are public-facing duties.’

The King is also said to have been forced to eat at least a light snack at lunchtimes after  skipping the meal his whole life.

Despite things getting almost back to normal – particularly on the surface, most notably with the King’s Speech last month – the Queen and the King’s closest aides are likely still urging him to take it easy as he continues on his road to recovery.
