WASHINGTON — During “a routine physical exam” at a Philadelphia hospital, a spokesperson confirmed to ABC News on Tuesday that a small nodule was discovered in former President Joe Biden’s prostate.

“In a routine physical exam a small nodule was found in the prostate which necessitated further evaluation,” a spokesperson told ABC News.

The discovery of a “small nodule” varies greatly in implications and necessitates additional testing to determine the underlying issue. Nodules are common in aging men. It is yet unclear whether the nodule is a benign lump due to inflammation or potentially something more concerning.

Back in February 2023, while he was still in office, Biden had a cancerous lesion removed from his chest, and prior to his presidency, he underwent Mohs surgery to remove several non-melanoma skin cancers.

“As expected, the biopsy confirmed that the small lesion was basal cell carcinoma,” White House physician Dr. Kevin O’Connor said at the time. “All cancerous tissue was successfully removed. No further treatment is required.”

“Basal cell carcinoma lesions do not tend to ‘spread’ or metastasize, as some more serious skin cancers such as melanoma or squamous cell carcinoma are known to do,” O’Connor explained. “They do, however, have the potential to increase in size, resulting in a more significant issue as well as increased challenges for surgical removal.”

O’Connor said the “site of the biopsy has healed nicely and the President will continue dermatologic surveillance as part of his ongoing comprehensive healthcare.”
