More than a year after the world learned of King Charles III’s cancer diagnosis, a wave of new concern has emerged regarding his long-term prognosis.

The monarch made history in February last year when he publicly disclosed his condition—a rare move in the traditionally private world of British royalty. While Buckingham Palace confirmed his illness, they withheld specific details about the type and stage of cancer, leaving many to speculate.

Since then, official updates on the King’s health have been sporadic at best. While some praised the Palace’s initial transparency, it has since returned to its usual reserved nature. As a result, royal watchers and insiders have filled the information gap with rumors and unconfirmed claims.

One such claim has recently reignited public concern. Journalist and royal commentator Camilla Tominey—well-known for breaking early stories about the royal family—told The Telegraph that sources close to the King believe his cancer is not curable.

According to Tominey, although King Charles’ current condition appears stable, it is unlikely that he will fully recover. “The discussion now is that His Majesty may live with cancer for many years to come, rather than be cured of it,” she explained.
