King Charles’s cancer treatment is ongoing, and today, he was hospitalized due to “temporary side effects.”

Buckingham Palace announced this evening, “Following scheduled and ongoing medical treatment for cancer this morning, the King experienced temporary side effects that required a short period of observation in hospital.” His engagements this afternoon were postponed, and tomorrow’s engagements will be rescheduled.

The Palace did not specify the nature of the side effects, adding, “His Majesty would like to send his apologies to all those who may be inconvenienced or disappointed as a result.” King Charles is currently back home at Clarence House, his London residence.

After his initial diagnosis in February 2024, Buckingham Palace said they would not be sharing what type of cancer Charles has, only specifying it was not prostate cancer. At the end of last year, a Palace source confirmed to T&C: “His treatment has been moving in a positive direction and as a managed condition the treatment cycle will continue into next year.”

There have been no updates on King Charles’s this year, though on a recent outing in Northern Ireland, he shared some advice with cancer patients. During his visit to Ulster University, the King asked those who were undergoing treatment if they were managing to “survive the side effects alright,” saying, “You just have to push on, don’t you.”

Early next month, King Charles and Queen Camilla are set to travel to Italy, though parts of their trip to the Holy See have been postponed following Pope Francis’s recent health scare.
