Family history and genes
Inside every cell in our body is a set of instructions called genes. These are inherited from our parents. Genes control how the body grows, works and what it looks like. If something goes wrong with one or more genes (known as a fault or mutation), it can sometimes cause cancer.
- You are two and a half times more likely to get prostate cancer if your father or brother has had it, compared to a man who has no relatives with prostate cancer.
- Your chance of getting prostate cancer may be greater if your father or brother was under 60 when he was diagnosed, or if you have more than one close relative with prostate cancer.
- You may have a higher risk of prostate cancer if your mother or sister has had breast cancer, particularly if they were diagnosed under the age of 60 and had faults in genes called BRCA1 or BRCA2.
If you have relatives with prostate cancer or breast cancer and are worried about your risk, speak to your GP. Although your risk of prostate cancer may be higher, it doesn’t mean you will get it.
