The palace added the cancer was identified during the King's recent time in hospital to undergo a corrective procedure for an enlarged prostate.
"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 statement said.
"Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual."
