What do we mean by risk?
There are different ways of explaining a man’s risk of getting prostate cancer. We already knew that Black men are three times more likely to develop prostate cancer than white men of the same age. This way of explaining risk is called relative risk and it means the difference in risk of one group of people compared to another. This information is still correct – it is just a different way of explaining a man’s risk of getting prostate cancer.
We also know that in general about 1 in 8 men will be diagnosed with prostate cancer at some point in their lives. This is a man’s lifetime risk of getting prostate cancer.
Lifetime risk means the risk that someone has of being diagnosed with the disease at some point during their life.
We know that people find lifetime risk a clear way of understanding their chances of getting a disease. So we decided to work out Black men’s lifetime risk of getting prostate cancer.
