Do You Know What Is Postate Cancer?
>> Friday, July 3, 2009
Prostate cancer is one of the prostate disorders found in men. It is a form of cancer that develops in the prostate, a gland in the male reproductive system. The cancer cells may spread from the prostate to other parts of the body, particularly the bones and lymph nodes.
Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse, or erectile dysfunction. Other symptoms can potentially develop during later stages of the disease.
Prostate cancer develops most frequently in men over the age of fifty and is one of the most prevalent types of cancer in men. However, many men that develop prostate cancer never have symptoms, undergo no therapy, and eventually die of other causes. This is because cancer of the prostate is, in most cases, slow-growing, and because most of those affected are from the age of 40-90. 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, have been implicated in the development of prostate cancer. The presence of prostate cancer may be indicated by symptoms, physical examination, prostate specific antigen (PSA), or biopsy. Further tests, such as CT scans and bone scans, 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. Other treatments such as hormonal therapy, chemotherapy, proton therapy, cryosurgery, high intensity focused ultrasound (HIFU) also exist depending on the clinical scenario and desired outcome.
The age and underlying health of the man, the extent of metastasis, appearance under the microscope, and response of the cancer to initial treatment are important in determining the outcome of the disease. 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.
