Causes of Prostate Cancer
Scientists have also studied whether other factors might increase the risk for prostate cancer, including:
- A virus passed through sex
- Lack of exercise.
At this time, however, these are not clear risk factors.
Also, most studies have not found an increased risk of prostate cancer for men who have had a vasectomy. A vasectomy is surgery to cut or tie off the tubes that carry sperm out of the testicles.
Most men who have known risk factors do not get prostate cancer. On the other hand, men who do get the disease often have no known risk factors, except for growing older.
If you think you may be at risk for prostate cancer, you should talk with your doctor. Your doctor may be able to suggest ways to reduce your risk and can plan a schedule for checkups.
