Does a Vasectomy Cause Prostate Cancer?
The American Medical Association has been sharing updated information concerning the lack of a link between vasectomy procedures and prostate cancer. The findings were published in the Journal of Clinical Oncology and were based on a study that followed participants from 1982 to 2012.
The study was actually designed to assess risk factors for many, many different types of cancer, prostate among them.
The reports suggest that, “there is no association between having a vasectomy and developing prostate cancer:
Results In the CPS-II cohort, vasectomy was not associated with prostate cancer mortality (HR, 1.01; 95% CI, 0.93 to 1.10). In the CPS-II Nutrition Cohort, vasectomy was not associated with either overall prostate cancer incidence (HR, 1.02; 95% CI, 0.96 to 1.08) or high-grade prostate cancer incidence (HR, 0.91; 95% CI, 0.78 to 1.07 for cancers with Gleason score ≥ 8).
Conclusion Results from these large prospective cohorts do not support associations of vasectomy with either prostate cancer incidence or prostate cancer mortality.
