WASHINGTON—Former President Joe Biden’s last known prostate-cancer blood screening test was performed in 2014, according to his spokesman, indicating that he wasn’t screened for the cancer during his four years as president.

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.

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.

Ezekiel Emanuel, a prominent Democratic figure, told “Morning Joe” the former president "did not develop [prostate cancer] in the last 100 to 200 days."

A recent physical exam revealed a small nodule in former President Joe Biden’s prostate, ABC News has confirmed. “In a routine physical exam a small nodule was found in the prostate which necessitated further evaluation,” a spokesperson told ABC News.

Trump Jr. suggests a coverup in the aftermath of Joe Biden's cancer diagnosis. He said Jill Biden, who doesn't have a medical degree, should've known.
