The specific mechanism leading to the presence of prostate cancer is still unknown but over the last years were identified certain risk factors that need to be carefully considered.
The risk increases with age because the cases of prostate cancers seldom appear at men under the age of 40; and it is established as a fact that this type of cancer is associated with the age group between 40 and 65 with the larger incidence over 65 years old.
It is a disease very frequent in North America and in the North East of Europe and very rare in Southern America, Orient and Africa.
In US, afro American males are by 37% more exposed to the risk than the Caucasian males, presenting the highest frequency in the world.
More and more connections are made every day between the prostate cancer and the diet rich in animal fat. A recent study demonstrated that the malign cells from the prostate cancer, inoculated on mice are developing 2 times slower on those whose diet contains less than 21% fat.
It is also considered that the difference between the diet habits explains the difference in the cancer frequency between USA and China, where animal fat is only a very small part of the daily diet.
The habitual factors like the professional exposure to cadmium were also associated to a risk factor.
The family heritage plays an important role and it is good to know that a man whose brother or father had prostate cancer has very good odds of developing the same cancer cells.
