We don’t yet know what causes prostate cancer, but we do know that it’s more common in : men over 50 men with a family history of prostate cancer (one or two “first-degree” relatives, such as a father or brother) men of African ancestry We also don’t know the effect that other factors (such as diets low in fibre or high in fat, or low levels of physical activity) have on the likelihood of developing prostate cancer.

While researchers still do not know the exact answer to this question, they have identified some risk factors. These include advancing age, race, genetics (heredity) and family history, and environmental factors such as toxins, chemicals, and industrial products. For more information, see the causes of prostate cancer.

The cause of prostate cancer is not known. However, certain factors can increase your risk of having prostate cancer including: • Age: The risk of prostate cancer increases with age. It is rare for a man under 40 to have it, but the risk increases rapidly after age 50: over 80% of all prostate cancers are diagnosed in men over 65 and 90% of prostate cancer deaths occur in men in this age group. • Race: Black men living in North America are at the greatest risk. Men of Asian ancestry are at lower than average risk. • Nationality: Prostate cancer is most common in North America and northwestern Europe. It is far less common in Asia, possibly due in part to dietary differences. • Family history: A brother or father with prostate cancer doubles your risk of getting it. Your risk increases further if more than one close relative is affected. • Diet: Studies have shown that a high intake of animal or saturated fats is associated with an increased chance of developing prostate cancer.

A risk factor is anything that increases a person’s chance of getting a disease. Different cancers have different risk factors. Some risk factors, such as smoking, can be controlled. Others, like a person’s age or family history, can’t be changed. But risk factors don’t tell us everything. Many people with one or more risk factors never get cancer, while others with this disease may have had no known risk factors. For some of these factors, the link to prostate cancer risk is not yet clear. Risk factors for prostate cancer Age: Age is the strongest risk factor for prostate cancer. The chance of getting prostate cancer goes up quickly after a man reaches age 50. Almost 2 out of every 3 prostate cancers are found in men over the age of 65. Race: For unknown reasons, prostate cancer is more common among African-American men than among men of other races. African-American men are also more likely to have a more advanced disease when it is found and are more likely to die of the disease. Pr

The exact cause of prostate cancer is not known. Men whose close relatives have had prostate cancer are more likely to get it, suggesting that there are genetic factors. Studies are being done to see if exposure to certain materials, such as the metal cadmium, increases the risk of developing prostate cancer. The effect of a high-fat diet is also being studied for its impact on prostate cancer.
