Queen Elizabeth II's husband, Prince Philip, has been diagnosed with prostate cancer but continues to carry out his duties despite the news, London's Evening Standard reported Wednesday.

Buckingham Palace issued a statement denying the Standard's report, which cites “medical sources” who claim the diagnosis was made back in April.

"The Duke of Edinburgh has authorized us to confirm that the claim made by the Evening Standard that he has received a 'diagnosis of prostate cancer' is untrue," the palace said in a statement.

The palace went on to say that the Standard's story was a serious breach of Prince Philip's privacy.

In April the 87-year-old spent three nights at a London hospital, where he allegedly received his cancer diagnosis. At the time, Buckingham Palace said he was treated for a chest infection.

"It's become an open secret within the medical community that Philip has prostate cancer,” an unidentified cancer specialist told the Standard.

"If he'd had a serious chest infection that was so worrying it required hospitalization, he wouldn't have walked in and out of there smiling and been 'sitting up in bed replying to letters.'"

On Wednesday, the prince was in Cowes on the Isle of Wight for the annual sailing week, the Standard reported.
