Despite his good mood during the ceremony, observers noticed a worrying detail: King Charles, who had interrupted his cancer treatment for this trip, is apparently suffering again from swollen hands and fingers. These symptoms have been plaguing him for some time, especially in warmer climates. The causes of the swelling can be varied, including the strain on the circulatory system from long-haul flights or water retention and arthritis. Charles has not elaborated on the causes of his symptoms, but in the past, he was not averse to joking about them. In a TV documentary about his coronation, for example, he joked on camera with his son Prince William, noting that he did not have "such sausage fingers like me".
Although Charles is not receiving treatments for his cancer during his trip, he is still accompanied by medical professionals. According to the "Sydney Morning Herald", the king is not only traveling with two doctors, but also has several blood reserves in his luggage, which were previously taken from him as an autologous blood donation.
