King Charles III, 75, has been diagnosed with cancer, Buckingham Palace announced Monday.
"During The King’s recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted," the palace said in an emailed statement. "Subsequent diagnostic tests have identified a form of cancer."
Buckingham Palace did not specify what form of cancer was diagnosed or at what stage it was found.
The news comes a week after both Princess Kate and King Charles were discharged from a private London clinic after medical procedures. The king underwent a “corrective procedure” for an enlarged prostate, while Kate, 42, had unspecified abdominal surgery on Jan. 17.
“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 added.
According to the statement, the king wanted to share his diagnosis in part to avoid speculation on his condition but also "in the hope it may assist public understanding for all those around the world who are affected by cancer."
Charles ascended the throne last May in a coronation ceremony held months after the death of his mother, Queen Elizabeth II. Elizabeth reigned until her death at the age of 96 in September 2022. She was Britain's longest-reigning monarch with 70 years on the throne.
Kate is still in recovery, but her husband, Prince William, is set to return to his royal duties by attending the London’s Air Ambulance Charity Gala Dinner on Wednesday.
Kensington Palace previously said the Princess of Wales is unlikely to return to her royal duties before Easter, on March 31. There was no date specified for the king’s return to duties.
