Researchers still do not know what causes prostate cancer. The role that some of the identified risk factors play in the development of prostate cancer is less clear, because research studies have provided conflicting results in some areas. Prostate cancer is twice as prevalent among African-American males as it is among their white American counterparts.
Prostate cancer is most common in North America and northwestern Europe.
It occurs less frequently in Asia, Africa, Central America and South America. The results of most studies show that men who eat a high fat diet have an increased chance of developing prostate cancer. Some research has shown that men who eat higher fat diets tend to eat less fruits and vegetables and more dairy products. These factors may also play a part in the development of prostate cancer. Maintaining a healthy weight along with regular physical activity may reduce the risk of prostate cancer.
