How does the new saliva test for prostate cancer work?
The new saliva test analyzes 130 genetic variants to assess the risk of aggressive prostate cancer. Unlike the PSA blood test, which measures a protein that can be elevated for various reasons, this saliva test provides a more precise genetic risk assessment, potentially leading to earlier and more effective treatment.

What are the advantages of this test over the PSA blood test?
The saliva test offers several advantages over the PSA blood test, including greater accuracy in detecting aggressive forms of prostate cancer. It reduces the likelihood of false positives and unnecessary treatments by identifying high-risk individuals more effectively. Additionally, being non-invasive, it may encourage more men to participate in screening programs.
