Former US president Joe Biden had not received a test for prostate cancer, known as a PSA, for more than a decade before he was diagnosed with an advanced form of the disease last week, a spokesperson said on Tuesday.
"President Biden's last known PSA was in 2014," the Biden spokesperson said on Tuesday. "Prior to Friday, President Biden had never been diagnosed with prostate cancer."
A PSA test, or prostate-specific antigen test, is a blood test that is used to screen for prostate cancer.
