A sexually transmitted infection has been linked to the development of prostate cancer in men, according to new sexual health research.
Inflammation which may be caused by trichomonas vaginalis appears to affect the progression of the cancer, stated the report carried out by the Harvard School of Public Health and researchers from Brigham and Women's Hospital.
The study showed that the infection was associated with more than a twofold rise in the incidence of advanced-stage prostate cancer.
Jennifer Stark, lead author of the study, said: "Identifying modifiable risk factors for the lethal form of prostate cancer offers the greatest opportunity to reduce suffering from this disease."
Research also associated the sexually transmitted infection with a threefold risk in the likelihood of the cancer being lethal.
The study was released this week in the online version of the Journal of the National Cancer Institute, which for several years has been the most-cited journal containing original research on cancer study.
