Following a positive PSA test, men usually must undergo further prostate testing to determine the exact nature of their growth. Most of the time, this means an invasive biopsy, which is one of the main reasons why men frequently avoid the doctor. However, a team of Australian researchers is looking at the possibility of using genetic testing to determine a growth's risk.
Researchers told Physorg that prostate growths produce a type of genetic material known as microRNA. They believe that it may be possible to test for these molecules. Their presence would indicate that a growth has the potential to become deadly.
They are currently checking various bodily fluids to see if prostate-related microRNA circulates throughout the body. If so, it may give doctors a window into their patients' prostate cancer risk without the need for putting them through an invasive biopsy.
"As there is minimal pain associated with the collection of saliva and urine, this would encourage more men to visit their local doctor and submit samples for prostate cancer screening," Dr. Nham Tran who is leading the investigation, told then news source.
Each year, more than 32,000 men die of prostate cancer, according to the National Cancer Institute. Experts blame many of these deaths on men's reluctance to seek prostate cancer testing.
