obese men have lower PSA values

Obese men are prostate cancer (cancer) index and PSA (prostate specific antigen) blood concentration is usually lower than the test results to adjust, but you must have known. The cause of the obese men, a lot of blood for PSA is diluted by the potential indicated by the American Medical bulletin "JAMA" November 21 issue reported.

Prostate cancer Fund (PCF) said that in the United States men's one out of six people in the prevalence of prostate cancer, the most in at least 65 years old. Many of the older men regularly received PSA blood tests, but a recent study from the excess weight and obesity in men with normal PSA values weight in males than 20 to 25 percent lower that were . Therefore, a large body of men, normally deemed to 1 to 2 years or more left while the cancer is growing and could have. Extremely underweight due to the impact of the presence or absence of PSA value of the deal were not disclosed.

The Duke University (NC) Associate Professor of urologic pathology Dr. Stephen Freedland said by this research is a large body of men's PSA value is low, the amount of blood due to the antigen was diluted by the to verify that hypothesis. 1988.From 1988 to 2006 between the removal of the prostate by prostate cancer examined patient 14,000 people about the result, the weight of so many men blood volume than is found. Diluted by PSA decrease in the level of having a theory and is backed by research group said.Freedland said the same thing to other blood cancer marker goes, "to develop a blood test for the product, it needs to take place," he said.

Meanwhile, the United States Medical University (New York) professor Nelson Stone, said the findings showed a skeptical view.This research has advanced prostate cancer patients, and only as a point of this and other factors will result in distortion might have said. However, a large body of people PSA value slimness and the same, but the value of PSA evaluation need to be careful that he also admitted.
