Major Risks for Prostate Cancer
Sunday, April 27th, 2008Prostate cancer is a tumor that arises in the prostate gland. If advanced or left untreated in early stages, this form of cancer can spread to other organs. Fortunately, prostate cancer is a slow growing form compared to other cancers and older men with the prostate cancer nearly always die of something else.
The major risk factors for prostate cancer are as follows:
- Age. Prostate cancer occurs almost exclusively in men after age 50.
- Genetic factors. Evidence suggests that men with a family history of the disease have a higher risk of developing prostate cancer.
- Ethnicity. African American men are known to have the world’s highest risk for prostate cancer, more than 50% higher than the risk for Caucasian American males. The death rates from prostate cancer are also higher among African Americans. The risks for prostate cancer among men who live in Asia are lower, with the tendency to increase if they move to North America. Thus, some environmental, social or dietary factors that can alter a man’s underlying genetic risk of developing this disease remain unknown.
- High exposure to chemicals and electromagnetic fields. Activities that involve exposure to certain metals and chemicals (including cadmium, dimethylformamide, and acrylonitrile), lubricating oils or greases, metal dust, or pesticides or garden sprays, put men at higher risk of prostate cancer.
- Infections. Some scientists suggest that there may be a relationship between prostate cancer and infections such as herpesvirus, human papillomavirus, and cytomegalovirus.
- Obesity. Obesity may increase the risk for prostate cancer or make it more difficult to diagnose.
- High-meat intake and high fat-intake. Some, but not all, studies have found some association between well-cooked meat and high-calorie intake.
