Technology Networks – A new blood test developed by researchers at the University of East Anglia (UEA) can detect prostate cancer with 94% accuracy.
Prostate cancer affects approximately 1 in 6 men, with 1 man dying every 45 minutes from the disease.
Current screening and diagnostic methods for prostate cancer include the prostate-specific antigen (PSA) test, among other, more invasive approaches.
PSA is produced by cancerous and noncancerous cells in the prostate, with small amounts circulating in the blood of healthy individuals.
If a patient presents with high levels of PSA in the blood, it can be indicative of cancer.
However, it might also be indicative of inflammation or enlargement of the prostate, affecting the reliability of the PSA test.
Professor Dmitry Pshezhetskiy from UEA’s Norwich Medical School says:
“There is currently no single test for prostate cancer, but PSA blood tests are among the most used, alongside physical examinations, MRI scans and biopsies.
“Only about a quarter of people who have a prostate biopsy due to an elevated PSA level are found to have prostate cancer.”
Developing a new blood test that has greater accuracy, and is also non-invasive and inexpensive, is a focus for researchers …
