The monarch has postponed a series of meetings and events, per doctor's orders.
King Charles III has sought treatment for an enlarged prostate.
On Wednesday, Buckingham Palace released a statement to ET regarding the 75-year-old monarch's health.
"In common with thousands of men each year, The King has sought treatment for an enlarged prostate," the statement reads. "His Majesty's condition is benign and he will attend hospital next week for a corrective procedure. The King’s public engagements will be postponed for a short period of recuperation."
It's said that the king wished to share the news of his diagnosis, in order to encourage men experiencing symptoms to get checked.
As for the King Charles' upcoming schedule, a royal source tells ET, "His Majesty had a series of meetings and events planned at Dumfries House tomorrow and Friday, which are now being postponed on doctor’s advice. Guests, including foreign dignitaries and members of the Cabinet, were due to travel and so they needed to make people aware of the situation."
ET has learned that Buckingham Palace does not expect that Counsellors of State will be needed at the time of the surgery. According to the Royal website, Counsellors of State are typically appointed in the event that The King cannot perform his official duties as Sovereign on a temporary basis due to illness or absence abroad.
News of King Charles' condition comes the same day it was revealed that his daughter-in-law, Kate Middleton, had abdominal surgery, and won't be doing any royal engagements until the spring.
"The surgery was successful and it is expected that she will remain in the hospital for 10 to 14 days, before returning home to continue her recovery," the Palace shared in a statement about the 42-year-old Princess of Wales. "Based on the current medical advice, she is unlikely to return to public duties until after Easter."
The Palace also noted that Kate "appreciates the interest" that this news will bring, but adds, "She hopes that the public will understand her desire to maintain as much normality for her children as possible; and her wish that her personal medical information remains private."
Kate shares three children with her husband, Prince William — Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5. With all of her pregnancies, the princess suffered from hyperemesis gravidarum, a condition which causes severe vomiting during pregnancy. It is unknown if that condition has anything to do with the abdominal surgery Middleton recently underwent.
