There is not a known single cause of prostate cancer. In general, most cancers are the result of many risk factors.However, some men with prostate cancer do not have any identifiable risk factors.
Independent factors include
- Men over 65: prostate cancer is not very common in men under 50.
- African ancestry: Men of African ancestry have a higher risk of developing prostate cancer. They have about a 60% higher rate of prostate cancer than Caucasian men. Men of African ancestry are more likely to be diagnosed at a younger age and with more aggressive and advanced tumor.
- Family history: the risk of developing prostate cancer is higher if a first-degree relative (father or brother) has been diagnosed with the disease.A Men are at the most risk if more than one relative has been diagnosed and if the relatives were diagnosed at a younger age. The risk doubles if a man′s father had the disease, and if a brother had it, the risk triples; hereditary prostate cancer typically begins among a cluster of relatives before age 55.
Dependent risk factors include
- High-fat diet: a diet high in fat, especially animal fat, may increase the risk of prostate cancer.
- Exposure to cadmium: Cadmium is a metallic element known to cause cancer and is a possible risk factor for prostate cancer.
