Monarch, 75, postpones public duties and returns to London for immediate treatment after medics spotted condition while he was undergoing surgery for enlarged prostate
King Charles has been diagnosed with cancer, Buckingham Palace announced in a statement this evening.
The 75-year-old monarch has returned to London from Sandringham to begin treatment immediately.
It is not connected with his recent surgery and is not prostate cancer, but medics spotted it when he underwent his medical procedure for an enlarged prostate.
The King is understood to have personally informed his sons Prince William and Prince Harry about his condition.
The Duke of Sussex will travel to the UK to see him in the coming days, a source close to Harry said.
Buckingham Palace said in a statement tonight: ‘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.
‘His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties. Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual.

‘The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure.
‘He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible.
