There is not one specific cause of prostate cancer, but there are some key factors that elevate the risk of developing prostate cancer.
Age: after age 50, chances of developing prostate cancer increase greatly. Nearly two out of three diagnosed men are over the age of 65.
Race: although the reason is not known, men of African or Caribbean descent are diagnosed more commonly, while men of Asian descent are less commonly affected.
Family history: the risk of developing prostate cancer is higher in men who have a history of the disease in their family.
Diet: men consuming high-fat, low-fibre diets are shown to have an increased risk for developing prostate cancer. Research suggests that diets high in saturated fats like processed foods, whole-milk, and fatty cuts of meat, increase the production of testosterone, which may assist in the growth of prostate cancer cells.
Prostate cancer can still develop even though none of these risks may be present.
