Tom Parker Bowles, son of Queen Camilla, gave a rare update on King Charles III's cancer treatment. The food critic reportedly made the revelation while promoting his new book, Cooking and the Crown: Royal Recipes from Queen Victoria to King Charles III.

According to the Express, Parker Bowles delivered the personal news at an event, saying that the King's “doctor says his treatment is going well.” Prince Charles announced that he had cancer in February 2024 and has since returned to official royal duties.

Parker Bowles also revealed how his mother, Queen Camilla, has dealt with the diagnosis, saying, “My mother is tough.”

Parker Bowles wrote an op-ed for the Daily Mail ahead of the book's release, in which he discussed King Charles and Queen Camilla's food preferences.

“No one knows more about food and farming than the King, from rare breeds of sheep and cattle to traditional varieties of plums, apples, and pears to the best British cheeses,” Bowles wrote, calling his father-in-law “a true food hero.”

Parker Bowles spoke of his mother and stepfather regularly eating healthy meals.

“Today, however, with the exception of state dinners and official dinners, the King and Queen, whether at Buckingham Palace, Sandringham Palace, or Balmoral Palace, eat simple, healthy, and resolutely seasonal food. Under the expert stewardship of Royal Chef Mark Flanagan, the chefs travel together."

Prince Charles, a big fan of sustainability, ensures that “there is no waste at the table” and “has long spoken about the importance of sustainable agriculture,” explained Queen Camilla's son.

“Like monarchs before him, his kitchen is filled with the seasonal bounty of the royal estate and garden, from game, beef, and lamb to peas, strawberries, raspberries, and chard,” Parker Bowles revealed. 'It is a tradition that has been handed down through the ages, along with the importance of tea for state dinners and as a mid-afternoon meal.'
