Prime Minister Justin Trudeau is wishing King Charles a speedy recovery after Buckingham Palace revealed the monarch has been diagnosed with cancer. 

Trudeau says after hearing the news, he's thinking about the King, just like countless others across Canada and around the world. 

The palace did not release additional details, except to say the cancer is not related to the King's recent treatment for a benign prostate condition. 

King Charles has already begun treatment and will postpone some of his public-facing duties, the palace noted, although he will continue to handle routine paperwork and matters of state. 

News of the diagnosis comes as his daughter-in-law Kate, Princess of Wales, recovers from abdominal surgery that saw her hospitalized for about two weeks.

The palace says the King is being treated as an outpatient.  

"I, like Canadians across the country and people around the world, am thinking of His Majesty King Charles III as he undergoes treatment for cancer," Trudeau said on social media. 

"We're sending him our very best wishes — and hoping for a fast and full recovery."

In a post of his own, Ralph Goodale, Canada's high commissioner to the United Kingdom, described the news as "troubling" as he wished the King a "speedy and complete recovery."
