For example, studies conducted among men who have a family history of prostate cancer, an attempt to identify genetic links to disease. Researchers in the long run, will try to block or modify the offending genes so as to prevent or modify disease. Finally, and perhaps a vaccine to prevent or treat prostate cancer will develop in the future. Prostate cancer is the second leading cause of cancer deaths among men in the United States. Although the causes of prostate cancer levaquin 500 mg prices are still unknown, several risk factors for diseases such as age and family history of prostate cancer have been identified. Prostate cancer is often initially suspected because of abnormal PSA blood test or a hard nodule (lump) felt on the prostate gland during a routine digital (done with a finger) rectal examination. Digital rectal examination (starting at age 40) and blood test for PSA (starting at age 50) must be made at yearly intervals to screen men for prostate cancer. Refinements in test PSA, including PSA ratio, age, PSA and PSA velocity or slope have improved the accuracy of the test. If one of the screening test is abnormal, the diagnosis of prostate cancer should be suspected and prostate biopsy is usually done. The diagnosis of prostate cancer is made when the cancer cells of prostate tissue biopsies detected in the microscope. In some men, prostate cancer is life threatening, while in many others, it may have existed for many years without causing health problems.
