In February, the palace revealed the 76-year-old, who became king in 2022, had been diagnosed with an unspecified form of cancer detected in tests after a corrective procedure for an enlarged prostate.
Last week, a palace source said his treatment was moving in a positive direction and would continue into next year.
For his annual pre-recorded Christmas Day broadcast to be aired on Wednesday, Charles has selected the Fitzrovia Chapel, an ornate former church on the site of a former hospital in central London.
"It is now a space for quiet reflection, discovery and celebration, connecting diverse communities from all faiths or none," Buckingham Palace said on X, adding that the king's grandfather George VI had laid the building's foundation stone in 1928.

The king's message will hail the hard work and dedication of healthcare workers as well as community cohesion in the wake of riots after the Southport stabbings according to media reports.
A royal source said the message would reflect on international, national and personal challenges and how they can be overcome by communities supporting one another.
The seasonal messages date back to a radio speech by his great-grandfather George V in 1932, and are usually filmed in one of the monarch's homes, with the late Queen Elizabeth last filming the broadcast outside a royal residence in 2006.
Last year, Charles delivered his message from Buckingham Palace.
The Daily Telegraph, which had earlier learned of the location, reported that Charles himself had chosen the chapel as he faced his own health issues.
A source told the paper the monarch wanted his message to feel fresher and more modern.
