Ce blood test was developed by British researchers. More accurate than current tests, this blood test is called « Prostate Screening EpiSwitch » ou PSE. Its purpose is to spot in the blood chromosomal conformations features of this type of cancer. The study carried out compared two groups of patients, those undergoing a standard test, PSA, and those undergoing the new PSE blood test. After analysis, the PSE tests, combining the two techniques, allowed find more prostate cancerwith a accuracy close to 94% (source 1).
