At 77, Charles expressed that reaching this stage in his recovery journey feels like “a personal blessing,” while also acknowledging “the remarkable strides in cancer care” that have been achieved in recent years.

His transparency about his diagnosis and efforts to raise awareness have been widely commended. Caroline Geraghty, a senior information nurse at Cancer Research UK, praised both Charles and his daughter-in-law, Catherine, Princess of Wales, for their openness in discussing their experiences with the illness.

“He’s actively engaged with hospitals, interacted with patients, and visited support centers. He has genuinely maintained a connection with many people,” Geraghty shared with CNN.

“He seems to feel, as do others, a shared experience with them. By sharing their stories, they emphasize that cancer does not discriminate; it can affect anyone, regardless of who they are,” she added.

King Charles has not publicly disclosed the type of cancer he has been receiving outpatient treatment for.

A royal source told CNN last year that the form of cancer detected was not prostate cancer, but did not specify further.

The spokesperson for the King told CNN on Friday that was because “the advice from cancer experts is that, in his determination to support the whole cancer community, it is preferable that His Majesty does not address his own specific condition but rather speaks to those affected by all forms of the disease.”

It’s not yet clear how much longer Charles will require treatment; that would be a matter for his medical team to determine.

Following his diagnosis last year, the King briefly stepped away from public facing duties, though he continued to carry out state business.

He has since returned to a busy diary of engagements and foreign trips.

“The King has taken great comfort and encouragement from being able to continue leading a full and active life throughout his treatment, while always heeding the advice of his medical team,” his spokesperson told CNN.

“His ability to uphold all of his state duties, and to continue with public engagements and overseas tours, has helped greatly with the positive mindset that, as many families will know, is such a vital part of the recovery journey.”
