King Charles III of Great Britain has been diagnosed with cancer, Buckingham Palace has announced.
The diagnosis was revealed recently as Charles underwent treatment at the London Clinic for a benign enlarged prostate.
In a statement, Buckingham Palace said: "During the King's recent hospital procedure for a benign enlargement of the prostate, an issue of particular concern was noted. Subsequent diagnostic tests have identified a form of cancer.
"His majesty has started a schedule of regular treatments today, during which time he has been advised by doctors to postpone duties with the public. Throughout this period, his majesty will continue to deal with state affairs and official documents as usual", the announcement further states.
"The King is grateful to his medical team for their quick intervention, which was made possible by his recent hospital procedure. He remains completely positive about his treatment and expects to return to full public duty as soon as possible.
"His Majesty has chosen to share his diagnosis to prevent speculation and in the hope that it may aid public understanding for all those around the world who are affected by cancer," the statement added.
Buckingham Palace has not released any further details at this stage.
It is understood that the diagnosis is not prostate cancer, as some may have mistakenly assumed in light of his separate diagnosis of benign prostatic enlargement.
The King returned to London from Sandringham this morning to begin outpatient treatment.
