Vasectomy and Prostate Cancer
Testicular cancer is much less common than prostate cancer, accounting for approximately 1 percent of all cancers in American men. This type of cancer is most often found in men ages 15 to 35. A few studies have suggested a link between vasectomy and an increased risk of testicular cancer, but the evidence is inconsistent, and the association in some studies may be due to factors other than vasectomy.
It is also possible that the vasectomy procedure increases the rate at which an existing, but undetected, testicular cancer will progress. At this time, it is believed that there is either no association or a weak association between vasectomy and testicular cancer, although more research is needed before definitive conclusions can be reached.
Men concerned about prostate cancer or testicular cancer should talk to their doctor about the prostate cancer symptoms and testicular cancer symptoms to watch for and an appropriate schedule for checkups.
