The news from Buckingham palace was shocking. Over a year after King Charles had announced that he had been diagnosed with cancer, the Palace issued a statement saying the King had experienced side effects from his treatment that were sufficiently severe to warrant observation in hospital.

King Charles is set for a 'usual working week' after he was briefly hospitalized on March 27 following a negative reaction to his routine cancer treatment, according to Buckingham Palace aides.

Buckingham Palace said that Charles experienced “temporary side effects” following treatment on Thursday and was taken to the hospital for observation before returning to his London residence.
