You are more likely to get prostate cancer if a close relative (father or brother) has had it. There are some other genetic factors that impact upon the risk of this type of cancer, but these cases are rare.
The risk of prostate cancer is higher in black men (1 in 4 black men will be diagnosed). It is not known why this is, but if you are a black man aged over 45, you should speak to your GP about your risk rate. For more information click here.
