A resurfaced video of Joe Biden appearing to say he had cancer three years ago has raised questions following his public diagnosis.

The announcement Sunday that former President Joe Biden was diagnosed with advanced prostate cancer has some people wondering how the disease could have been missed.

It’s aggressive. The cells have an ugly, disordered appearance under a microscope. Pathologists gave them a Gleason score of 9 (out of 10) for their likelihood to advance quickly. The cancer has already moved from Biden’s prostate to his bones, which means it cannot be cured — only controlled with drugs.

Former President Joe Biden did not release the results of a prostate-specific antigen blood test that could have caught his prostate cancer before it became aggressive.

Former President Joe Biden’s “last known” prostate cancer screening was in 2014, and he had never been diagnosed with the disease before last week, his office said Tuesday.

After maintaining a low profile since leaving the White House, former President Joe Biden recently emerged with media interviews and an April speech.
