A genetic analysis indicates the probability of dying from prostate cancer.

Do you want to know your risk of dying from prostate cancer? The answer, according to a study published in ‘Nature Communications’, can be given by a simple genetic analysis. A team of Japanese researchers from the Riken Center assures that it is enough to analyze a small portion of a person’s genome to estimate the probability that they will die from prostate cancer, even before suffering from the cancer. Prostate cancer is the second most common cancer in men worldwide. It also has the highest heritability among all common non-skin cancers, indicating that a man’s genetics play an important role in whether he will get the cancer. That makes it an ideal candidate for genetic studies. Related News standard No A system fattens tumor cells to diagnose cancer early R.

The results will help identify people at high risk early in life. In this work, the power of genetic studies has been applied to prostate cancer in a study that includes data from 300,000 people. The team focused on sites that bind the male hormone androgen, as a preliminary analysis revealed that variants of those sites played a dominant role in prostate cancer. They also assessed the risk of dying from prostate cancer rather than the risk of getting the disease. The results obtained indicated that the polygenic risk score developed in the study can be used to predict the future risk of dying from prostate cancer. Furthermore, they showed that androgen receptor binding regions of normal prostate cells are particularly effective in predicting this. Unlike many previous studies that focused on people of European origin, the study used data from Japanese, which, Terao notes, makes the “findings generalizable.” The study results will help identify high-risk people early in life, who can then be tested more frequently throughout their lives.
