King Charles III has been diagnosed with cancer and began treatment on Monday, Buckingham Palace says.
The Palace says the cancer was identified during the King’s recent hospital treatment for a benign enlarged prostate.
“A separate issue of concern was noted,” the Palace says, and “subsequent diagnostic tests have identified a form of cancer”
The Palace has not said what type of cancer the King has been diagnosed with.
Prince Harry has spoken to his father and will travel to the UK from the US in the coming days.
Charles, 75, has been advised to postpone public duties, but will “undertake state duties” and paperwork.
He is being treated as an out-patient, and is at home in London on Monday evening, the Palace says.
