A devastating health update regarding King Charles‘ health has emerged.

The beloved monarch, 76, first revealed to the public that he was battling cancer over 18 months ago.

At the time, Buckingham Palace released a statement which read: “During the King’s recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted. Subsequent diagnostic tests have identified a form of cancer.”

Since this announcement, King Charles has put on a brave face for the public and continued his royal duties.

However, a palace insider has issued a heartbreaking update regarding the 76-year-old’s cancer battle.

Royal insider Camilla Tominey, who was the first to report on Meghan Markle and Kate Middleton‘s fall-out, claims to The Telegraph that sources have informed her that King Charles’s cancer is ‘incurable.’

Although it’s not clear what type of cancer he has, it’s previously been reported that it was caught at an early stage.

She says that while the monarch’s cancer is currently under control, it is ultimately incurable.

“The talk now is that he may die ‘with’ cancer, but not ‘of’ cancer following a rigorous treatment program,” Tominey told The Telegraph.

The insider added that there are ‘tentative’ plans in place for King Charles’ 80th birthday in 2028.

Due to his health struggles, Tominey revealed that King Charles will never move into Buckingham Palace. He and his wife, Queen Camilla, currently reside at Clarence House.

These fresh claims come after King Charles’ son, Prince Harry, sparked speculation about how long the monarch had left in his BBC interview.

At one point in the interview, the Duke of Sussex said: “Life is precious. I don’t know how much longer my father has.”

King Charles himself addressed his cancer battle just weeks ago, telling a royal fan that he was ‘on the other side’ of his health crisis.

Elsewhere in the report, it’s claimed that the monarch and Prince Harry’s much-discussed reunion could finally take place at the Invictus Games in Birmingham, U.K., in 2027.

It’s believed palace aides are looking into a potential reunion, which would hopefully involve Prince Harry and Markle’s children, Archie and Lilibet, who King Charles hasn’t seen since 2022.
