WASHINGTON -- A representative for former President Joe Biden said he last took a prostate-specific antigen blood test, commonly used to screen for prostate cancer, in 2014.

The PSA test is a blood test used primarily to detect prostate cancer. According to the Mayo Clinic, the test detects prostate-specific antigen (PSA) levels in the blood. PSA is a protein generated by malignant and non-cancerous cells in the prostate, a tiny gland located under the bladder in males.

Prostate cancer highlights from AUA 2025 include quality-of-life results from the phase 3 PSMAfore study, findings on ADT with or without darolutamide, and data on the PSMA-targeted radionuclide J591.
