men developing advanced cancer.
"These people are all going to die, they are going to die incredibly expensively and die miserably," he said, referring to the many men whose diagnoses would be delayed by not testing. "I don't know that all these people could be saved with PSA testing," but many could, he added.
But Messing disagreed with that advice. Condemning PSA testing "wasn't a brilliant conclusion," he Nike Air Max Uptempo 2
"At best, only one of these 1,000 men who were screened avoids dying from prostate cancer for at least 10 years," LeFevre said. "In addition, about one in every 3,000 men screened dies as a result of surgery to treat cancer detected by the PSA test."
But the USPSTF maintains the benefits of testing are overrated. "The task force recommends against prostate cancer screening using the PSA test, as the potential benefit does not outweigh the harms," said Dr. Michael LeFevre, co vice chair of the task force and professor in the department of family and community medicine at the University of Missouri School of Medicine.
The report was published online July 30 in the journal Cancer.
Using these cases Nike Uptempo Red Mens as a base, the researchers constructed a model that used data of advanced cancer diagnosed in the 1980s and predicted how many cases of advanced cancer would have been diagnosed in 2008 if PSA testing was Nike Air Uptempo Black
threatening, which is why testing is controversial. Preventive Services Task Force (USPSTF) in May recommended against routine PSA screening, saying too many non lethal cancers were being treated aggressively, exposing men who didn't need treatment to serious side effects such as impotence and urinary incontinence.
Messing said the annual number of prostate cancer deaths dropped from about 42,000 in the 1990s to 28,000 now. "The only thing that can explain that is PSA early detection and treatment," he said.

Messing advises men with a family history of prostate cancer or urinary symptoms to have a PSA test. Men with no family history or symptoms should discuss PSA testing with their doctor, he added.
Messing pointed out that screening detected cancer doesn't mean surgery, chemotherapy or radiation treatment must follow. Most cases can be watched for some time, he said.
said. Surveillance, Epidemiology, and End Results database for the years 1983 to 1985 immediately before widespread PSA testing started to data from 2006 through 2008.
Testing, on the other hand, might keep some 17,000 men each year from receiving a diagnosis of late stage prostate cancer cancer that has spread and is far less curable the study finds.
As a result of treatments for PSA detected prostate cancer, one out of 1,000 men screened in the United States develops a blood clot in his legs or lungs, two will have a heart attack or stroke, and up to 40 are left impotent or with urinary incontinence, LeFevre said.
In the 2008 data, 8,000 cases of prostate cancer were diagnosed after the malignancy had spread to other parts of the body.
Their model showed instead of 8,000 actual cases in 2008, about 25,000 cases would have been diagnosed.
Still, the task force recognizes that "some men may continue requesting the PSA test and some physicians may continue offering it," LeFevre said.
Abandoning PSA Screening Could Cost Lives
"PSA testing, for all its pluses and minuses and all that . . . permits you to catch the disease earlier," said lead researcher Dr.
Before getting this blood test which measures a protein in cells of the prostate gland men should learn about the pros and cons, he said. "The decision to start or continue screening should reflect an understanding of the possible benefits and known harms, and should respect each individual's preferences."
