Thanks to ultrasound in the U.S. prostate cancer mortality fell by

The death rate from prostate cancer in the United States declined as always uses ultrasound, but it does not prove that such a test is necessary. On that occasion, argue American and British scientists. Ultrasound is used in the U.S. is much higher than in the UK, for this reason, U.S. researchers believe that the death rate is four times lower in their country of prostate cancer. What British scientists respond that many other factors affect the risk of prostate cancer, and not rely solely on ultrasound. Many men over 80 years, diagnosed with prostate cancer die, but it does not mean that the disease was the cause of death. Potentially other diseases contributed death, the British scientists. The use of ultrasound and blood test does not mean that these measures save lives men, say scientists from the University of Bristol. According to them, while American scientists argue that ultrasound is to reduce the number of deaths, they can only speculate and look for other risk factors, because you can not rely on these measures.
