Buckingham Palace released an official statement announcing King Charles III has been diagnosed with cancer. The diagnosis was made while the British King was undergoing treatment for a benign enlarged prostate at The London Clinic. 

The prognosis or stage have not been revealed to the public, but the announcement says His Majesty will be postponing public facing duties and only continue to "undertake State business and official paperwork" The palace did specify The King does not have prostate cancer. 

The King returned to London on Monday to begin out-patient care, and "remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible," the palace said.

According to BBC, there's a "constitutional mechanism for when the head of state is unable to carry out official duties - in that circumstance "counsellors of state" can be appointed to stand in for the monarch." This includes Queen Camilla, Prince William, Princess Anne and Prince Edward.

The monarch informed his sons and siblings personally about his diagnosis and it's in constant communication with Prince William.

The Duke of Sussex, who currently lives in the United States, will be traveling to the United Kingdom to see his father in the coming days. 

The release says His Majesty decided to publicly share his diagnosis to primarily prevent speculation, but also in hopes it "may assist public understanding for those around the world who are affected by cancer." 

The king was last seen in public at Sandringham on Sunday to attend a church service with the queen.
