After screening tests including a digital exam and blood work, a person with a nodule or enlarged prostate may be referred to a urologist for a biopsy, which takes small tissue samples to look for cancer.

The exact cause of the prostate nodule has not been shared with the public, and it may not be wise to jump to conclusions, considering it can either be cancerous or benign -- caused simply by an enlarged gland.

WASHINGTON (AP) — A small nodule was found in the prostate of former President Joe 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.
