A “small nodule” was reportedly found in former President Joe Biden’s prostate following “a routine physical exam” at a hospital in Philadelphia last week.

The discovery on Friday has “necessitated further evaluation,” a spokesperson for the former president told ABC News. A spokesperson declined to share any additional information about his care when reached by The New York Times.

It’s common for older men to experience prostate issues. Biden, who is 82, was the oldest serving U.S. president when he left office in January.

A nodule is a growth or lump that may be cancerous or non-cancerous, and requires further testing. Prostate cancer is the second most common cancer among men in the U.S., the first being skin cancer. Out of 100 American men, about 13 will get prostate cancer in their lifetimes, and about two or three will die, according to the Centers for Disease Control and Prevention.

When caught early, prostate cancer is highly treatable, however, according to the American Urological Association, which estimates that more than half of all prostate cancer is found in people older than 65.

Biden’s age was a point of concern and contention throughout his administration, with critics repeatedly raising questions about his physical health and cognitive abilities. Amid mounting pressure and calls from some Democrats for him to pass the baton, he ultimately ended his reelection campaign less than four months before the 2024 election.

Biden and his wife, former first lady Jill Biden, earlier this month pushed back on claims that his declining health was behind his departure from the ballot.

“The only reason I got out of the race was because I didn’t want to have a divided Democratic Party. It’s a simple proposition,” he said on “The View.”

Biden’s personal physician, Dr. Kevin O’Connor, had repeatedly given him a stellar health report during his time in office and declared him to be in “excellent” condition just days after his dropped campaign.

A book set for release next week claims Biden’s administration repeatedly concealed declines in his physical health from the public, however, and that at one point there were internal discussions about having him use a wheelchair.
