On May 13, 2024, King Charles III publicly shared that he has experienced side effects from cancer treatment, specifically losing his sense of taste, during a joint appearance with Prince William at the Army Flying Museum in Middle Wallop, Hampshire. King Charles, aged 75, was diagnosed with an undisclosed type of cancer in February 2024 after a check-up revealed an unrelated, benign enlarged prostate. The side effect revelation occurred during a conversation with Aaron Mapplebeck, a British Army veteran and cancer survivor.
In the same event, King Charles officially transferred the honorary command of the Army Air Corps from Prince Harry to Prince William. This regiment was Prince Harry’s former unit, where he served during his second tour in Afghanistan in 2012. The transition of roles was perceived as a setback for Prince Harry when initially announced last year.
Furthermore, King Charles unveiled a plaque to mark the display of an Apache AH Mk.1 helicopter at the museum, recognizing the aircraft's involvement in a 2007 rescue mission during the Battle of Jugroom Fort.
The joint engagement marked one of the rare public insights into King Charles’s private health battle and served as a significant occasion, reflecting both ceremonial duties and personal challenges within the royal family.
