A small nodule found in 82-year-old former US President Joe Biden’s prostate during a routine exam has raised public curiosity.

One usual method would be to do a PSA test. Alternatively, he could have a new urine test that looks for genetic signals of cancer. Doctors could examine Mr. Biden’s prostate with an MRI, or ultrasound. “Ultimately, if they think this nodule is prostate cancer, the final step would be a biopsy,” Dr. Moul said.

A small nodule was found in the prostate of former President Biden during a routine physical exam, a spokesperson said Tuesday. A short statement said the finding “necessitated further evaluation,” but it was not clear whether that had already taken place or the outcome of the examination.
