How the Science managed to understand the causes of prostate cancer?

The study of prostate cancer has come a long way since its identification in 1853. Information on diagnostic methods, treatments, and even the pathophysiological characteristics of this disease, which is taught in detail useful to researchers, but the specific causes of prostate cancer is not known at this time.

The causes of prostate cancer, cancer or any other, remained a mystery for the students of the disease. Despite the situation develops, the process by which prostate cancer is explained, the exact reasons for the emergence of the disease a challenge to cancer researchers.

Prostate cancer is a disease that only affects men. The prostate, the part of the male sex organs helps to make and store the semen. It surrounds part of the urethra and is located below the bladder and in front of the rectum. Its location makes it possible to influence the process of urination, ejaculation and defecation.

Although the causes of prostate cancer could not be fully understood, scientists are some factors to identify at risk for developing the condition. Possibilities of human prostate cancer are influenced by their age, genes, race, bring diet, lifestyle and medication. Prostate cancer is rare in men under 45. But the chances of developing prostate cancer at the age of man.
Based on statistics of patients with prostate cancer, 70 is collected, the average age of diagnosis.

Prostate cancer is a slow evolution of this problem. Some men who do not even have it the condition that he may die of other causes before their cancer occurs. But one man, one first-degree relative like a brother or father who was diagnosed with this disease is of the opinion that it was more likely prostate cancer, especially if the report was diagnosed at age develop early.

Among the race have African-Americans to take account of known, a higher proportion of diagnosed cases of prostate cancer. Asians, meanwhile recorded the lowest number of cases diagnosed. The researchers speculate that this may be the difference between diet and lifestyle of the people of West Asia y. Westerners tend to have more red meat, while Asians often eat vegetables and fruit. Men with higher short-chain fatty acid linolenic acid has been found that higher rates of prostate cancer. Other dietary factors have been in the development of prostate cancer associated elements such as low consumption of vitamin E include, lycopene, omega-3 fatty acids and selenium.

In terms of genetics, not a single gene has not yet been proven responsible for the development of cancer of the prostate, although BRCA1 and BRCA2, two risk factors of ovarian and breast cancer in women.

Although the causes of prostate cancer has not yet been fully identified, there is great hope that the exact process that the disease eventually understood and provides preventative methods to reduce the number of men with the help requirement.
