King Charles cancer: Queen says he's 'doing extremely well' as treatment for unknown cancer continues

Queen Camilla has made her first public comments on her husband King Charles' condition after he was diagnosed with cancer this week. 

While the nature of the cancer has yet to be made public, Buckingham Palace has confirmed it is not prostate cancer. 

At a charity event at Salisbury Cathedral in Wiltshire, Camilla was asked: "I do hope HM is doing well, Ma'am?" 

She was then heard to reply that Charles had been "touched" by the public support. 

"He is doing extremely well under the circumstances. He is very touched by all of the letters and messages the public have been sending from everywhere. That's very cheering," she said. 

It is believed Camilla has not left her husband's side since his diagnosis and has been with him in Norfolk as he recuperated. 

On Thursday, Charles' son Prince William became the first royal to publicly acknowledge the diagnosis. 

He thanked the British public for their well wishes while at a gala event in London, saying, "We really appreciate everyone's kindness" when asked about his health. 

On Tuesday, Buckingham Palace announced the King had been diagnosed with the disease but didn't state anything further about his condition.     

In a statement, the palace said that during the King's recent time in hospital to undergo a corrective procedure for an enlarged prostate, a "separate issue of concern" was found.   

"Subsequent diagnostic tests have identified a form of cancer," the statement said. 

Meanwhile, the King has apologised to his subjects in Grenada as they celebrated their 50th year of independence, referencing briefly his illness. 

He apologised he could not "be with you in person" to celebrate the "momentous milestone".  

He also said that he holds "special memories" after visiting the island five years ago. 

Charles has yet to publicly say more about his illness.
