LONDON — King Charles III has been diagnosed with cancer, Buckingham Palace has announced in a statement.

“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,” Buckingham Palace’s statement saidMonday. 

It did not elaborate on the type of cancer but said the king, who is 75, began treatments Monday.

Doctors advised him to postpone public-facing duties but he will continue state business and official paperwork, the statement said.

“The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure,” the statement said.
