A simple blood test or urine test can help in identification of prostate cancer. The scientists at the University of California found that 7,783 men suffered from disease called prostrate cancer and 38, 595 men were free from any kind of disease. In order to make it the largest research project in the US, they examined about 1,00,000 volunteers and took all the necessary factors like genetic, health and environment that could influence some common diseases like prostate cancer into consideration. The researchers used 105 specific bits of DNA that varies among all the individuals and confirmed if a person was affected with prostate cancer or not.
The genetic variants of individuals differed from each other moderately. A combination of DNA variants found men to be more prone to this risk and more than six times, they were diagnosed with prostate cancer. The UCSF professor of epidemiology and biostatics developed a risk model that had good value. He also said that some genetic risk factors have not been discovered yet. Men were more prone to the risk of prostate cancer compared to breast cancer risks where mutation in one gene of breast cancer took place. Women who are suspected of mutated BRCA genes are available for genetic testing commercially. At present, there is no clinical test available to measure the risk of prostate cancer in people. The addition if one DNA base pair was located on chromosome 6 in almost 30 percent of the population.
