huh? who says it doesn't and why do they say such? they must be referencing a specific- primary preventive? secondary? tertiary ? a screen testing? annual check-up?.........?

our long list of 'diseases of civilization ' (with diabetes at the forefront) can be attacked from a lifestyle standpoint . In time patients symptoms and need for pills likely vanish depending on degree of disease. We're talking reversing high blood pressure, auto-immune , type 2 diabetes, skin illness,..etc

The study is a follow-up to one of the two in 2009 that looked at prostate-specific antigen (PSA) testing, and it confirms that men who receive regular PSA tests do not live longer than men without regular screening. Both the 2009 study and the follow-up, published in the Journal of the National Cancer Institute (JNCI), use data from the same Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. But the new study updates the old one, confirming the finding that there’s still no mortality difference between the screened and non-screened groups, even after the roughly 75,000 men in the study have been followed for 13 years.

Breast cancer screening in “real world” situations is not effective in preventing mortality, says a US case control study. The study, one of the largest completed to date looking at the effectiveness of breast cancer screening, was published in the Journal of the National Cancer Institute (2005;97: 1035-43).

Doubts deepened further this year, when a study of almost 90,000 women — one of the largest clinical trials ever conducted — found that mammograms not only offer no benefit to younger women, but pose a risk by increasing detection and treatment of otherwise harmless tumors.

Prostate Cancer Screening Shows No Benefit [regular P.S.A. testing does not save lives and can lead to aggressive treatments that leave men impotent, incontinent or both.]
I will stop there. There is no doubt preventive care does not save money, it is unclear that it "saves lives" (people are killed as a result of preventive care) at the aggregate.

well, anyway headed out for the evening i'll fire this. Ace appears to be concerned both with cost-effectiveness and efficacy of two screening tools for two prevalent health issues - prostate cancer and breast cancer. HUGE concerns for both , agreed. In addition the usefulness of a yearly physical. Right? I don't think Ace is saying preventive care has no part to play in health, be it primary prevention (ex., vaccination , polio is no longer an issue in N America), secondary preventive care (care given AFTER a diagnosis and treatment , ex. placing a cardiovascularly compromised patient on ASA or anti-coagulants) and tertiary prevention (goal to improve quality of life for folks with long-term advanced disease, ex. stroke rehabilitation programs).

you may find the following a good read Ace. Science keeps evolving . Do we want tools to pick up disease at its early stages? of course we do. Prostate cancer detection may have a new tool ,
http://publishing.aip.org/publishin...method-non-invasive-prostate-cancer-screening
Cancer screening is a critical approach for preventing cancer deaths because cases caught early are often more treatable. But while there are already existing ways to screen for different types of cancer, there is a great need for even more safe, cheap and effective methods to save even more lives.
Now a team of researchers led by Shaoxin Li at Guangdong Medical College in China has demonstrated the potential of a new, non-invasive method to screen for prostate cancer, a common type of cancer in men worldwide. They describe their laboratory success testing an existing spectroscopy technique called surface-enhanced Raman scattering (SERS) with a new, sophisticated analysis technique called support vector machine (SVM).
As they described in a new paper in Applied Physics Letters, from AIP Publishing, they combined SERS and SVM and applied them to blood samples collected from 68 healthy volunteers and 93 people who were clinically confirmed to have prostate cancer. They found their technique could identify the cases of cancer with an accuracy of 98.1 percent.
If the technique proves safe and effective in clinical trials, it may become a new method available to patients and their doctors, helping to improve the early detection and diagnosis of this type of cancer, said Li.
“The results demonstrate that label-free serum SERS analysis combined with SVM diagnostic algorithm has great potential for non-invasive prostate cancer screening,” said Li. “Compared to traditional screening methods, this method has the advantages of being non-invasive, highly sensitive and very simple for prostate cancer screening.”
A COMMON CAUSE OF CANCER
According to the World Health Organization, prostate cancer is one of the most common types of cancer in men worldwide and a leading cause of cancer-related death. Every year, there are about 899,000 new cases and 260,000 mortalities, comprising 6 percent of all cancer deaths globally. About 1 in every 6 men will develop prostate cancer over their lifetimes.
While a simple blood test for elevated levels of a protein marker known as prostate specific antigen (PSA) has been used for years to screen for early cases of prostate cancer, the test is far from perfect because the elevated PSA levels can be caused by many things unrelated to cancer. This contributes to over-diagnosis, uncomfortable tissue biopsies and other unnecessary treatment, which can be costly and carry significant side effects. Because of this, the U.S. Preventative Services Task Force now recommends against PSA-based screening for prostate cancer.
According to Li, many scientists have thought about applying SERS to cancer detection because the surface-sensitive type of spectroscopy has been around for years and is sensitive enough to identify key molecules in very low abundance, like pesticide residues on a contaminated surface. This would seem to make it perfect for spotting subtle signals of DNA, proteins or fatty molecules that would mark a case of cancer -- exactly why he and his team tackled the problem.
The challenge, he said, was that these changes were, if anything, too subtle. The signal differences between the serum samples taken from the 68 healthy volunteers and the 93 people with prostate cancer were too tiny to detect. So to accurately distinguish between these samples, Li’s group employed a powerful spectral data processing algorithm, support vector machine (SVM), which effectively showed the difference.
While the work is preliminary, it shows that serum SERS spectroscopy combined with SVM diagnostic algorithm has the potential to be a new method for non-invasive prostate cancer screening, Li said. The next research step, he added, is to refine the method and explore whether this method can distinguish cancer staging

With the Super Bowl just a week away, the need for VitD to instigate Polyforum arguments with his BP ghost will be removed.
Coming soon - multipage Threads with dozens (dare I say Hundreds) of traded insults from Vit & his ghosts lobbed at JoeContrarian and his ghosts.
At least we will have the Willie/AK contest thread wherein we can chat sports with a mix of AceBB utterly offtopic slime posts bragging about his extensive education, his giant bank account and of course his enormous pecker
good times can still be found in the ol' Rx basement

Eye check ups, good preventive medicine.

to detect cataracts
can indicate Diabetes (changes seen on the Retina, haemorrhages and exudate's)
can indicate high blood pressure ( silver and copper wire vessel changes, haemorrhages and exudate's,papilloedema)

Can detect tumours of retina both benign and malignant.
