King Charles’s cancer treatment will continue into 2025, although it is moving “in a positive direction,” sources say.

The Buckingham Palace source said, “His treatment has been moving in a positive direction, and as a managed condition, the treatment cycle will continue into next year,” Sky News reported.

The insider also said there was a sense of optimism surrounding the King’s treatment, as shown by his desire to keep a full schedule of engagements despite the diagnosis.

In February, the King announced he had been diagnosed with a form of cancer and had begun a schedule of regular treatments, prompting well-wishes and praise for his candour about his health difficulties.

Since then, he has been receiving regular treatment, which he paused with the approval of doctors in October to allow himself and Queen Camilla to complete their jam-packed royal tour of Australia and Samoa. He then resumed the treatment when he returned to the UK.

On the trip – which was described as a “perfect tonic” for the monarch – the King did not shy away from talking about how his health and doctor’s orders had stopped him from visiting places in the Commonwealth as soon as he would have liked.

After the tour, it was also confirmed that if given the green-light by doctors, Charles, 76, will continue a full royal tour schedule next year.

A Senior Palace official said at the time: “We’re now working on a pretty normal looking full overseas tour program for next year, which is a high for us to end on, to know that we can be thinking in those terms – subject to sign off by doctors. It is hard to overstate the joy that he takes from duty and service and being in public and seeing those crowds engaging with communities across the spectrum. That really does lift the spirits. You can see that.”

The King will end the busy year next week by hosting Christmas for the Royal Family at Sandringham, with 45 people set to attend the celebrations.
