About Prostate Cancer

By: yousef

The reason of calling this disease in this name is that the cancers attack the prostate, which is a gland in the male reproductive system. The reason of this disease is a change occurs in the prostate and it starts to multiply more than the normal. It's possible that the infected cells these cells may expand to other parts of the body, specifically the bones and lymph nodes.

Prostate cancer rates are varying widely beyond the world. And these rates also vary widely among countries, it is not very common in South and East Asia, you can find it more common in Europe, and most common in the United States. According to the American Cancer Society, prostate cancer is least common among Asian men and most common among black men, with number for white men in-between. However, these high rates may be affected by increasing rates of detection.

Prostate cancer grows mostly in men over fifty. This cancer can attack only in men, as the prostate is exclusively of the male reproductive tract. It is the most common type of cancer in men in the United States, where it is responsible for more male deaths than any other cancer, except lung cancer. However, many men who develop prostate cancer never have symptoms, undergo no therapy, and eventually die of other causes. Many factors, including genetics and diet, have been implicated in the development of prostate cancer.

Prostate cancer is most often discovered by physical examination or by screening blood tests, such as the PSA (prostate specific antigen) test. There is some current concern about the accuracy of the PSA test and its usefulness. Suspected prostate cancer is typically confirmed by removing a piece of the prostate (biopsy) and examining it under a microscope. Further tests, such as X-rays and bone scans, may be performed to determine whether prostate cancer has spread.

Prostate cancer can be treated with surgery, radiation therapy, hormonal therapy, sometimes chemotherapy, proton therapy, or some combination of these. The age and underlying health of the man as well as the extent of spread, appearance under the microscope, and response of the cancer to initial treatment are important in determining the outcome of the disease. Since prostate cancer is a disease of older men, many will die of other causes before a slowly advancing prostate cancer can spread or cause symptoms. This makes treatment selection difficult.[5] 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.
