Circumcision May Help Protect Against Prostate Cancer
(Ivanhoe Newswire) -- Infections are known to cause cancer, and in males, sexually transmitted infections may contribute to the development of prostate cancer. Now, a new analysis has found that circumcision before a male's first sexual intercourse may help protect against the deadly disease.
Researchers at Fred Hutchinson Cancer Research Center found certain sexually transmitted infections can be prevented by circumcision. Certain infections can lead to prostate cancer by causing chronic inflammation that creates a hospitable environment for cancer cells.
They found circumcision may protect against sexually transmitted infections, and therefore prostate cancer, by toughening the inner foreskin and by getting rid of the moist space under the foreskin that may help pathogens survive.
"Although observational only, these data suggest a biologically plausible mechanism through which circumcision may decrease the risk of prostate cancer. Future research of this relationship is warranted," lead author Jonathan L. Wright, M.D., an affiliate investigator in the Hutchinson Center's Public Health Sciences Division, was quoted saying.
