They are germs. They are very small and they get confused quite easily. However, bacteria and viruses are two very different things. And in order to effectively fight against those that cause the disease, it is better to clearly identify them.

prostate cancer Cancer is the most common cancer in men in France. More than one in two men are concerned after age 65. Anticipating the development of cancer and its aggressiveness is a challenge for doctors. Researchers from the University of East Anglia in the UK have made an interesting discovery in the urine and prostate tissue of men with prostate cancer. , we got many types bacteria associated with aggressive shape prostate cancersome of which are new bacterial strains never discovered before , Rachel Hurst explainsFirst author of the study.

Five bacteria implicated in prostate cancer?

The scientists analyzed urine and tissue samples from 600 men with and without prostate cancer. to isolate bacteria Sampling, sequencing methods were used and made it possible to image bacteria living near the prostate and urinary tract. Among them, five new anaerobic bacterial strains (ie those that grow only in the complete absence of oxygen) are associated with an increased risk of prostate cancer.

Scientists are already envisioning testing it screening where a certain type of bacteria is present in urine And prostate cancer can be a warning sign for the progression of prostate cancer. The causal link between the presence of bacteria and the aggressiveness of prostate cancer has yet to be formally demonstrated, which, if true, may promise a real breakthrough in the management of the disease, which affects approximately 8,000 patients each year. kills men.
