King Charles III visited a cancer treatment center in London on Tuesday, marking his first public engagement since he announced his cancer diagnosis three months ago. He spoke to patients about his own shock upon receiving the diagnosis, offering sympathy and encouragement. His wife, Camilla, accompanied him on the visit. The palace announced last week that Charles is continuing treatment, but has made enough progress to resume some public engagements, which will be limited and adapted to accommodate his recovery. The King was diagnosed with cancer following a prostate operation earlier this year. His treatment is ongoing, although the palace reports that his doctors are satisfied with his progress. This is the first royal health scare to affect the British monarchy in many years, and has led to speculation and discussions about the royal family's role and structure.
