In addition, typical theories include the usual, diet, exercise, ethnic originality and genetics.

Diet is an important factor, a high-fat diet increases the chances of getting prostate cancer, particularly animal fats. However, case studies have shown that other various fats found in our everyday food can be linked to prostate cancer, including that of vegetable fats. On the upside however, there are foods that we can introduce mor strongly into our daily diet to decrease our risks. Omega-3 acids, which are found in oily fish contain minerals that studies have shown to decrease the risk. A higher intake of tomatoes for example has also been shown to have positive results, Vitamin D and soy intake has also been linked to claims of decreasing your risk. But, as with any claim, they are currently being investigated and many trials and experiments will be required before any solid cases and treatments can be derived from these.

Furthermore, another typical theory that has cropped up has been the nature of your ethnic background; typically african-american and latino men have a higher risk of developing prostate cancer than of Caucasian men. As with, Asian and Native americans, being the least likely to develop prostate cancer. Such theories have been linked directly to the diets of those ethnic backgrounds, the further west you come in the world, the higher the risk of developing this cancer seems to become, as opposed to men who are from the Africas and Asias.

Another third, and final theory, stems from a family history of prostate cancer. Studies have shown that people with direct relatives in the family that have developed cancer are at a higher risk of developing it themselves, particulary fathers or brothers. However, numerous factors can cause such developments, such as mutations in genes are known to initiate growths. Men who carry the BRCA 1 and BRCA 2 may have doubled their risk of developing prostate cancer. Men with high levels or testosterone are also likely targets of this cancer, so, it's always advisable to get checked up.
