King Charles back in London: start of “groundbreaking’ cancer treatment?. King Charles III landed his royal helicopter on the grounds of Buckingham Palace, British media reported.

He then drove to his current place of residence, Clarendon House. The actual palace is currently being renovated. It is not clear what form of cancer Charles is suffering from. However, it is known that it is not prostate cancer. Charles announced last week that he would postpone all public duties. But insiders had revealed that the king was well enough for a limited number of personal meetings.
