Stephen Fry has praised King Charles for sharing news of his cancer diagnosis.

The 75-year-old monarch was recently diagnosed with "a form of cancer" following a "corrective procedure" for an enlarged prostate, and Stephen has now hailed the King for being so transparent about his diagnosis.

The 66-year-old actor told 'The Today Podcast': "Like any taboo, it's sort of mushroom-like. In the dark, it grows. It's more dangerous when not exposed to the light."

Despite this, Stephen has confessed to feeling "anxious" for his friend.

The actor - who underwent an operation to treat prostate cancer back in 2018 - shared: "I am anxious, of course, anxious for his wellbeing and anxious that ... having sort of been in the wings all this time and to have such a short time on centre stage, if he were to be seriously ill, would be really, really sad, because he has a lot to do and a lot he wants to do.

"I think what he wants to do is good, is beneficial for the country and for the people he's there to help."

Charles' cancer diagnosis was revealed to the public earlier this week.

Buckingham Palace explained that the monarch wanted to share the news "in the hope it may assist public understanding for all those around the world who are affected by cancer".

A statement read: "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. Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual.

"The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure. He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible.

"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."
