Vasectomy is a surgical procedure that prevents men from fathering children. Some studies have suggested that vasectomies increase the risk of prostate cancer, although other studies failed to find such a link. Symptoms of Prostate Cancer Prostate cancer can grow quietly for years, which means most men with the disease have no obvious symptoms. When cancer grows through the prostate capsule, it invades nearby tissues. Because prostate cancer tends to metastasize to the bone, bone pain, particularly in the back, can be another symptom of prostate cancer.
Some doctors recommend screening for prostate cancer.
Screening, as distinct from diagnosis , looks for signs of disease in people who have no cancer symptoms. Screening for prostate cancer is controversial, because it is not yet known if the process actually saves lives, and it is not always clear that benefits outweigh the risks of diagnostic tests and treatments. The higher a man's PSA level, the more likely that cancer could be in the picture. Among the remaining 15 men, only 3 will have biopsies that show cancer. Neither PSA nor DRE accurately identifies all cancers.
