The purpose of this study was to determine the incidence of prostate cancer in patients who have an elevated referral prostate-specific antigen (PSA), which subsequently falls to within their ...

As David James, the director of Prostate Cancer Research, explains, the PSA test measures the levels of a prostate-specific antigen, a protein made by cells within the prostate.

However, recent research found prostate cancer in men with PSA levels below 4.0 ng/mL Some researchers have suggested lowering the PSA cutoff levels.

A new study shows that combining PSA levels with MRI-derived periprostatic fat measurements improves high-grade prostate ...

A new test for prostate cancer that measures levels of prostate specific antigen (PSA) as well as six specific antibodies found in the blood of men with the disease was more sensitive and more ...

PSA levels appear to be more predictive of three year prostate cancer risk in African-American men compared with Caucasian men with a family history of prostate cancer, according to new research.

The controversy around PSA testing is it can over-diagnose low-risk prostate cancers that would never become life-threatening. PSA tests may also give false positive results when someone doesn't ...
