London, March 27, 2025 – King Charles III was briefly admitted to The London Clinic on Thursday after experiencing temporary side effects related to his ongoing cancer treatment. Buckingham Palace confirmed that the 76-year-old monarch required hospital observation following a scheduled treatment session.
Brief Hospital Stay and Recovery
The King was discharged later the same day and returned to his London residence at Clarence House. A palace spokesperson reassured the public that His Majesty was in “good spirits” and continued to oversee state affairs from home.
“Following a routine treatment session, the King experienced mild side effects that required a short period of medical observation. He has since returned home and is continuing his duties,” the statement read.
Postponement of Engagements
Due to this health episode, Buckingham Palace announced that some of the King’s scheduled engagements for Thursday and Friday had been postponed. This included diplomatic meetings with ambassadors and planned public events in Birmingham.
“The King extends his apologies to those affected and looks forward to rescheduling his commitments in due course,” the statement added.
Ongoing Cancer Battle

King Charles was diagnosed with an undisclosed form of cancer in February 2024. The illness was discovered during treatment for an enlarged prostate, though Buckingham Palace clarified that the cancer was unrelated to his prostate condition. Since then, he has been undergoing regular medical treatment while maintaining a reduced but active schedule.
Despite his diagnosis, the King has continued to fulfill many of his royal duties, including private meetings with government officials and ceremonial obligations. His recent appearance at Commonwealth Day celebrations earlier this month underscored his commitment to public service.

Impact on Royal Responsibilities
While the King remains dedicated to his duties, senior royals, including Queen Camilla and Prince William, have stepped in to handle additional responsibilities. The Prince of Wales has been seen taking on a more prominent role, representing the Crown at key events.
According to palace sources, the King’s upcoming state visit to Italy in early April is still expected to proceed as planned, though officials will continue to monitor his health closely.
Public and Political Reactions
News of the King’s hospitalization has drawn widespread public concern and messages of support from world leaders and citizens alike. British Prime Minister Rishi Sunak wished His Majesty a swift recovery, acknowledging his resilience amid health challenges.
“We all wish the King well and look forward to seeing him continue his service to the nation,” said the Prime Minister in a statement released by 10 Downing Street.
Royal commentators have noted that the King’s transparency regarding his health is a shift from the traditionally private approach taken by previous monarchs. His decision to continue working while receiving treatment reflects his commitment to duty, they say.
Health and Support for Cancer Patients

King Charles’ diagnosis has also sparked public conversations about cancer awareness and treatment. The National Health Service (NHS) has encouraged individuals to seek regular check-ups and early screenings, emphasizing the importance of timely medical intervention.

Looking Ahead
As King Charles continues his treatment, the monarchy remains steadfast in its operations. While some of his engagements may be adjusted, he remains actively involved in governance and state affairs. His next public appearance is anticipated in the coming weeks, pending medical clearance.
