Doctors are looking closely at the link between common viruses and prostate cancer. A large review of 57 reports found that men with prostate cancer were much more likely to have detectable HPV, specifically the high-risk types 16 and 18. This finding suggests a strong connection between the virus and the cancer.
However, the evidence is not perfect. Because the data came from many different studies with different methods, the certainty of these results is very low. While the link to HPV is clear in the data, it does not mean the virus causes the cancer or that current medical habits need to change.
For now, these findings do not mean that doctors should change how they screen for infections or recommend vaccines for prostate cancer prevention. The study highlights a strong association, but it does not prove that changing sexual behavior or getting a vaccine will lower cancer risk.
Common questions
Does having HPV increase the risk of prostate cancer?
The study found that men with prostate cancer were much more likely to have detectable HPV, including types 16 and 18. However, the researchers noted that these results do not prove that the virus causes the cancer, and the overall certainty of the data is very low.
Should I get an HPV vaccine to prevent prostate cancer?
The findings in this study do not support making changes to current medical recommendations. This means that HPV vaccination, STI screening, or changes in sexual behavior are not currently recommended as ways to prevent prostate cancer based on this data.
What other infections were linked to prostate cancer?
The study looked at other factors like Trichomonas vaginalis and past history of STIs. However, the results for these specific infections were inconsistent or unclear, so they do not provide a clear link to prostate cancer at this time.
