In general, men with a family history of prostate cancer have a relatively high risk of developing prostate cancer.
A patient with prostate cancer has an increased risk of developing it in male relatives, including brothers, sons, cousins, and nephews. The younger the patient is when prostate cancer is diagnosed, the higher the risk of prostate cancer in his male relatives, and the earlier the onset of the disease.
The risk of prostate cancer in male relatives is higher if there are multiple family members diagnosed with prostate cancer.
So men with a family history of prostate cancer can start screening for prostate cancer earlier than age 45, including a rectal exam and serum PSA test, which can be done once a year. Also pay attention to your diet, quit smoking and drinking, eat a less high-fat diet, and eat more fruits and vegetables to reduce the risk of prostate cancer.
