The former president’s cancer diagnosis prompted an outpouring of well wishes and sympathy, as well as some whispered uncertainties that reflected a lack of trust in what he says about his health.

“Last week, President Joe Biden was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms. On Friday, he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” the statement from Biden’s office said.

David Axelrod suggested on Sunday that discussions about Joe Biden's mental acuity should be set aside following the former president being diagnosed with cancer.

Solemn reactions are flowing in following the announcement that former President Joe Biden has an aggressive form of prostate cancer. Even President Donald Trump – who normally only invokes his predecessor’s name to blame him for something – posted that he was “saddened to hear about” the diagnosis.

Commentator Hugh Hewitt said Democrats "screwed up" by not stating the extent of former President Joe Biden's cognitive decline.

The former US president has been diagnosed with an aggressive form of prostate cancer that has spread to his bones, his office says.

Reckoning ahead? After a lifetime in public office, the former president faces a perilous cancer diagnosis and difficult questions.

The news that former President Joe Biden has been diagnosed with an "aggressive" form of prostate cancer has raised fresh questions about his White House's transparency. Biden's office said in a statement on Sunday that he was diagnosed with prostate cancer on Friday, with the cancer cells having spread to the bone.
