What does 'comparative risk' mean in prostate cancer?

Mark Vogel (Board Certified Urologist) gives expert video advice on: Who should get a prostate cancer screening?; Why is early prostate cancer detection important?; What are the symptoms of prostate cancer? and more...

Well, we look at prostate cancer as one of the most common malignancies in men, and one of the most common causes of cancer related deaths in men, and therefore an important cancer to screen for. The factors that would make us be more inclined to screen would be, for example, someone who has a family history of prostate cancer. Screening for other cancers when there are risk factors, such a lung cancer in a smoker, can be important, but prostate cancer is such a common disease we think it's important to screen for that disease.
