Now the people who may have to go through painful procedures for the prostate cancer screening may not need to experience such issues. Until now, patients were screened for prostate cancer through protein specific antigen test. However, a new research from the Guangdong Medical College Doctors in China could lead to an easy non-invasive blood test for prostate cancer screening.
Researchers say the newly discovered non-invasive test uses a combination of two existing techniques. They are the SERS (Surface-enhanced Raman Scattering) and SVM (Support vector machine).
The researchers said they had a 98.1 percent success rate for the accuracy of the detection of prostate cancer detection.
Dr Shaoxin Li, the lead researcher in this study in a statement said, “Compared to traditional screening methods, this method has the advantages of being non-invasive, highly sensitive, and very simple for prostate cancer screening.”
The study involved the blood samples of 68 healthy individuals and 93 patients affected by prostate cancer. Based on the phenomenon of Raman scattering researchers has applied the SERS imaging technique on the patients after which the chemical nature of the particular substance can be analyzed. The same technique was proved successful when applied on brain tumors to detect the affected tissues.
Prostate cancer is among the most common cancers found among men in the United States and also across the world according to WHO. While the detection of prostate cancer for decades through PSA tests was successful, there were also false positive cases. However if the second stage of the SERS spectroscopy study proves to be beneficial, then the same non-invasive procedure may also be followed in the United States for the screening of prostate cancer.
