Royal Comeback: King Charles Set to Reveal Progress in Cancer Battle as 'Treatment Going Well' for 75-Year-Old Monarch

King Charles III's cancer treatment, which started in February, is said to be going "well," with reports suggesting His Majesty could reveal the type of the disease he has been battling.

"Never say never," a royal source told an outlet about the possible disclosure. "There are no current plans to reveal the cancer. But if he felt that the time was right..."

"It wasn’t like he was totally broken nor are we totally out of the woods yet as treatment continues," they added. "Treatment has gone better than anyone would have thought even in their most optimistic thoughts."

Another insider optimistically replied, "The sun wasn’t shining in February but it is shining now."

These insights follow and counter recent reports that highlight how HM's cancer "hasn't gone away," and although the sovereign is "still unwell," the royal machine is ensuring "it is being fantastically well managed to give the impression that everything is fine," a source spilled.

The royal insider added how the "once-popular notion that he will live to a similar age" of his parents Queen Elizabeth II and Prince Philip, is "now less widespread." The late queen and her consort were 96 and 99 when they died, respectively. The King is 75, and on September 8, he will commemorate his second year as Britain and the Commonwealth's monarch on "Accession Day," but another insider claims it will be bittersweet.

"It's a sad day for a reigning monarch anyway since it also signifies the anniversary of one of their parents or family members' passing," they stated. "But for His Majesty, he will likely also be contemplating his life and what remains of it, we simply do not know how severe his cancer could or could not be. He will never abdicate, he firmly believes in the oath of life service."

They concluded: "So inevitably all eyes turn to Prince William and Kate — they will become King and Queen the moment Charles III dies, and things are not going great for the Princess of Wales either."

The future queen is reportedly still receiving complex, preventative chemotherapy treatments to stave off cancer cells presumably in the area of her January abdominal operation.

"Kate has been exceptionally open and honest about her health," a friend of the Prince and Princess of Wales told a publication. "Making two appearances before the summer break, at Wimbledon and Trooping the Colour, was a clear signal that she is doing well. That is what we are hearing privately as well — it’s not over but there is lots of optimism, lots of positivity."

They added: "It is obviously still an incredibly worrying time but all the signs are that her cancer treatment, which is ongoing, is progressing well."
