Bacteria can cause cancer, this is the case withHelicobacter pylori for stomach cancer. A recent discovery suggests that five bacterial strains may be involved in prostate cancer. Are they related to the most aggressive forms of this male disease?
theis the most common cancer in men in France. More than one in two men is concerned after 65 years. Anticipating the evolution 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 found several types of associated with aggressive shapes some of which are new bacterial strains never discovered before », first 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 thesamples, sequencing methods were used and made it possible to draw a portrait of the bacteria living near the prostate and the urinary tract. Among them, five new anaerobic bacterial strains (ie which develop only in the total absence of oxygen) are associated with an increased risk of prostate cancer.
This discovery raises many questions. ” Some of the things we don’t yet know are how people get these bacteria, whether they cause cancer or whether a badallow their growth “says Rachel Hurst. If there seems to be a link between the aggressiveness of cancer and the presence of these bacteria, the underlying mechanisms have yet to be determined.
Scientists are already imagining a test ofwhere the presence of a certain type of bacteria and the prostate could be a warning signal for the progression of prostate cancer. The causal link between the presence of the bacterium and the aggressiveness of prostate cancer has yet to be formally demonstrated, promising, if true, a real breakthrough in the management of this disease which kills around 8,000 men every year. year.
