| Rates of prostate cancer vary widely across the world. Although the rates vary widely between countries, it is least common in South and East Asia, more common in Europe, and most common in the United States.<ref>{{cite web | url = http://web.archive.org/web/20060205235509/http://www.jncicancerspectrum.oxfordjournals.org/cgi/statContent/cspectfstat;99 | title = IARC Worldwide Cancer Incidence Statistics—Prostate | publisher = Oxford University Press | work = JNCI Cancer Spectrum | date = December 19, 2001}} Retrieved on 2007-04-05 through the Internet Archive</ref> Prostate cancer develops most frequently in men over fifty. This cancer can occur only in men, as the prostate is exclusively of the male reproductive tract. It is one of the most common types of cancer in men. However, many men who develop prostate cancer never have symptoms, undergo no therapy, and eventually die of other causes. That is because malignant [[neoplasm]]s of the prostate are, in most cases, slow-growing, and because most of those affected are over 60. Hence they often die of causes unrelated to the prostate cancer, such as heart/circulatory disease, pneumonia, other unconnected cancers or old age. Many factors, including [[genetics]] and [[Diet (nutrition)|diet]], have been implicated in the development of prostate cancer.

| Prostate cancer is most often discovered by PSA ([[prostate specific antigen]]) screening and less commonly by [[physical examination]] or by symptoms. There is some current concern about the accuracy of the PSA test and its usefulness. Suspected prostate cancer is typically confirmed by taking a [[biopsy]] of the prostate and examining it under a [[microscope]]. Further tests, such as [[CT scan]]s and [[bone scan]]s, may be performed to determine whether prostate cancer has spread.

| Treatment options for prostate cancer with intent to cure are primarily [[surgery]] and [[radiation therapy]].

The decision whether or not to treat localized prostate cancer (a tumor that is contained within the prostate) with curative intent is a [[patient trade-off]] between the expected beneficial and harmful effects in terms of patient survival and quality of life.

Overview
Prostate cancer is a disease in which cancer develops in the prostate, a gland in the male reproductive system. It occurs when cells of the prostate mutate and begin to multiply out of control. These cells may spread (metastasize) from the prostate to other parts of the body, especially the bones and lymph nodes. Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse, erectile dysfunction and other symptoms.
