"His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties," the Royal Household said in a statement.

It made the announcement after the 75-year-old king underwent treatment for an enlarged prostate at a hospital in late January.

The king has chosen to share his diagnosis "to prevent speculation and in the hope it may assist public understanding for all those around the world who are affected by cancer," the statement said.

He will continue to undertake state business and official paperwork as usual, it added.

Charles became king after his mother Queen Elizabeth II died in September 2022.
