A drop of blood can help detect pancreatic cancer. Though prostate cancer is also identified through blood tests, a high PSA (prostata protein) value doesn’t always denote the disease.
Enter a London-based research team and its new test which uses the DNA in saliva to predict patients’ prostate cancer risk.
The test is based on a study which relied on DNA from hundreds and thousands of men and analysed genetic variations linked with prostate cancer.
The spit test detected 55.1% of aggressive cancers compared with 35.5% using the standard PSA test. It’s also more accurate than an MRI scan.
Saliva provides information on oral cancer, too. One day, it might be possible to reverse cancer.
