People Editorial Guidelines Updated on April 26, 2024 03:47PM EDT King Charles is gearing up for a return to public-facing royal duties after revealing his cancer diagnosis in February. Buckingham Palace shared an encouraging update about the monarch's health on April 26, announcing that King Charles, 75, will visit a cancer treatment center to meet medical specialists and patients with Queen Camilla, 76, on April 30. It's understood that the center has not been directly involved with the King's medical care. The palace added that the outing will be the first of several engagements planned for the King in the coming weeks, including hosting a state visit at Buckingham Palace for the Emperor and Empress of Japan in late June. After beginning cancer treatment, King Charles postponed public duties but continued to work behind the scenes and undertake meetings including small audiences at Buckingham Palace. However, a royal source previously told PEOPLE that the monarch's desire to work was "wholly undiminished" with his nephew Peter Phillips revealing in an interview that his uncle was "frustrated" by his limitations.

" Peter said. “So the overriding message would be that he's obviously very keen to get back to a form of normality. And he's probably frustrated that, recovery is taking a little longer than probably he would want it to." A Buckingham Palace spokesperson said that King Charles' cancer treatment will continue, but "doctors are sufficiently pleased with the progress made so far that The King is now able to resume a number of public-facing duties."

His appearance at Trooping the Colour, the annual celebration and parade marking the British monarch's birthday in London, on June 15 is still unconfirmed, in addition to other highlights on the royal calendar such as Royal Ascot in June and palace garden parties in May. "Any public-facing engagements will be announced nearer the time in the usual way and will remain subject to doctors’ advice," the palace spokesperson said. "His Majesty is greatly encouraged to be resuming some public-facing duties and very grateful to his medical team for their continued care and expertise," the spokesperson added.
