Experts said it is not unusual that Biden’s aggressive prostate cancer, revealed May 18, 2025, went undetected.

MSNBC anchor Joe Scarborough refused to walk back his previous defense of former President Joe Biden‘s health even after it was announced Biden has “aggressive” prostate cancer. Scarborough stood by his analysis of Biden following their hourslong interview in March 2024.

President Donald Trump strongly suggested that Joe Biden hid his prostate cancer diagnosis from the American people when opining on the news, adding that the alleged omission is worthy of investigation. “It’s a very, very sad situation. I feel very badly about it. And I think people should try and find out what happened,” Trump said Monday.

Biden, even after he has exited political life and as he faces a serious cancer diagnosis, remains a factor in the conversation about his party's political future.

After a stretch of limited public appearances since leaving office, former President Joe Biden’s cancer diagnosis arrived amid heightened scrutiny of his cognitive health.
