King Charles has been diagnosed with cancer and will be taking a step back from public-facing duties, Buckingham Palace has announced.

The monarch says he feels “wholly positive” about his treatment and will “continue to undertake state business and official paperwork as usual”.

In a statement, Buckingham Palace said: “During The King’s recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted. Subsequent diagnostic tests have identified a form of cancer.

“His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties.”

“His Majesty has chosen to share his diagnosis to prevent speculation and in the hope it may assist public understanding for all those around the world who are affected by cancer.”

The King previously received treatment for an enlarged prostate at London Clinic on Friday, January 26 and was discharged last Monday after three nights.

Charles was diagnosed with the benign condition on January 17 while staying at Birkhall, Aberdeenshire, after going for a check-up because he was experiencing symptoms.

The King attended a church service for the first time since his treatment in hospital on Sunday at St Mary Magdalene Church in Sandringham alongside Camilla.

Last week, the Queen said her husband was “doing his best” following his release from hospital as she opened a cancer support centre at the Royal Free Hospital in London.

Earlier on Monday, it was announced the Prince of Wales would carry out his first public engagements since the Princess of Wales underwent major abdominal surgery in January, also at the London Clinic.
