Two and a half years have passed since Buckingham Palace revealed, in February 2024, that King Charles III had cancer. Since that announcement, which sparked a wave of emotion in the United Kingdom and well beyond, the exact nature of the British sovereign's illness has never been specified, and it likely never will be. According to La Depeche, this opacity is deliberately maintained by the palace, which has made the king's state of health one of the most tightly guarded subjects of the British monarchy.
This choice of silence is nothing new in the history of the royal family. Unlike other heads of state or public figures whose health is the subject of detailed medical bulletins, the British monarchy has always cultivated a form of institutional modesty around the sovereign's body. This tradition, which goes back several generations, aims to preserve both the dignity of the royal function and a form of symbolic stability in the eyes of public opinion, in a country where the monarch embodies continuity above individual vicissitudes.
The sparse information released by Buckingham Palace over the past eighteen months nonetheless points in a rather encouraging direction. According to details reported by La Depeche, Charles III's state of health is said to have improved over the months, to the point that his treatment was reportedly reduced. This positive development would partly explain the gradual resumption of his public engagements, with the king stepping up official appearances, trips abroad and ceremonial duties despite the illness.
That said, no details have emerged about the type of cancer the monarch has, nor about the stage at which it was diagnosed at the time of the initial announcement. The palace had at the time simply stated that the illness had been detected during a separate surgical procedure, related to a benign enlargement of the prostate, without ever confirming that the cancer concerned that organ. This deliberate ambiguity, maintained ever since, has fuelled speculation in the British and international press for two and a half years.
La Depeche points out that this question has become, in its own words, "the world's best-kept secret". A phrase that reflects the scale of the confidentiality arrangements put in place around the king's medical file, in a context where the British monarchy nonetheless remains one of the most closely watched institutions on the planet, with an extremely active royal and celebrity press in the United Kingdom.
This withholding of information is also part of a broader calculation of institutional communication. By never revealing the precise nature of the cancer, Buckingham Palace avoids feeding interpretations about the real severity of the illness, its prognosis, or the king's ability to continue carrying out his duties over the long term. This strategy of vagueness also allows the palace to control the media narrative, releasing only general and reassuring information, such as that of a reduced treatment, without ever giving outside medical experts material for more in-depth analysis.
