"One potential risk factor is inflammation, which appears to play an important role in the development
and progression of prostate cancer, but the source of inflammation of the prostate is not clear.
Trichomonas vaginalis, which infects an estimated 174 million people globally each year
and is the most common non-viral sexually transmitted infection,
can infect the prostate and could be a source of inflammation.
With respect to prostate cancer prevention, it is noteworthy that up to three-quarters of men infected with Trichomonas vaginalis
may not realize they are infected, since they may not have any symptoms...
The results showed that Trichomonas vaginalis infection was associated with a more than two-fold increase
in the risk of prostate cancer that was advanced stage at diagnosis,
and a nearly three-fold increase in prostate cancer that would result in death",
