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 form of this male disease?

[EN VIDÉO] What are the differences between bacteria and viruses? They are microbes. They are very small and can be easily confused. However, bacteria and viruses are two completely different things. And to effectively fight those who cause the disease, it is better to clearly identify them.
The prostate cancer It is the most common type of cancer in men in France. More than two cases (66%) involved a man over 65 years of age. Anticipating the progression and aggressiveness of cancer is a challenge for clinicians. Researchers from the University of East Anglia in the UK have made an interesting discovery in the urine and prostate tissues of men with prostate cancer. ” We found several types of bacteria associated with aggressive forms Prostate cancerSome of them are new bacterial strains that have not been discovered before “,” Rachel Hurst explainsfirst author of the study.
Five bacteria involved in prostate cancer?
The scientists analyzed urine and tissue samples from 600 men with and without prostate cancer. to isolate bacteria Samples and sequencing methods were used and made it possible to draw a picture of bacteria that live near the prostate and urinary tract. Among them, five new anaerobic bacterial strains (that is, those that develop only in the complete absence of oxygen) are associated with an increased risk of prostate cancer.
This discovery raises many questions. ” Some of the things we don’t know yet are how people become infected with these bacteria, whether they cause cancer or whether they are bad immune response let them grow If there appears to be a link between the aggressiveness of cancer and the presence of these bacteria, the underlying mechanisms remain to be determined.
Scientists are already imagining a test Detective Where there is a certain type of bacteria in urine The prostate can be a warning signal for the development of prostate cancer. The causal relationship between the presence of bacteria and the aggressiveness of prostate cancer has yet to be formally proven, and it is promising, if true, for a real breakthrough in the management of this disease that kills about 8,000 men each year.
