King Charles III diagnosed with cancer, Buckingham Palace says

King Charles III has been diagnosed with cancer following a recent hospital stay for prostate surgery, according to a statement released from Buckingham Palace.

The palace unveiled the diagnosis on Monday, saying the 75-year-old monarch has already begun treatment without specifying what form of cancer he has, only confirming it is not related to the king’s recent treatment for a benign prostate condition.

“During The King’s recent hospital procedure, a separate issue of concern was noted,” reads the statement. “Subsequent diagnostic tests have identified a form of cancer.”

The king will step back from his duties as Monarch while he undergoes treatment, according to the statement. The palace says he decided to share his diagnosis to prevent any speculation.

“His Majesty will continue to undertake State business and official paperwork as usual,” the palace says. “He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible.”

Charles was discharged from a private London clinic last week, following a three-night stay, after undergoing a “corrective procedure” for an enlarged prostate.

He was diagnosed with the benign condition on Jan. 17 after he experienced undisclosed symptoms. The king decided to announce the surgery in advance in an effort to encourage other men to have their prostates checked in line with public health advice.

Charles was admitted to the same hospital as his daughter-in-law Kate Middleton, the Princess of Wales, who had abdominal surgery. She was discharged the same day.

The palace did not provide further details on her condition but did confirm it was not cancerous.

Prime Minister Justin Trudeau joined a chorus of well-wishers from Canada and around the world on Monday in wishing Charles a speedy recovery.

Gov. Gen. Mary Simon said she, like all Canadians, is sending good wishes to the King as he begins treatment. In a statement, Simon praised the monarch for leading by example in choosing to share his diagnosis.

Charles ascended the throne 16 months ago after the death of his mother, Queen Elizabeth II. Speculation about the health the late queen increased during the last months of her 70-year reign as undisclosed “mobility issues” limited her public appearances.
