The U.S. Preventive Services Task Force (USPSTF) recently released a 2017 draft recommendation statement on screening for prostate cancer which is based on systematic evidence review and assessment— updated from their prior 2012 version. As indicated by the authors’ viewpoint published in JAMA, the goal of this release is to raise awareness of newly acquired data on the topic while inviting review and commentary before the report is officially finalized.

Because there was concern that universal PSA (aka prostate-specific antigen, a blood test) population screening often...

In a recent article, actor Ben Stiller chronicled how early diagnosis of prostate cancer - by a routine Prostate-Specific Antigen (PSA) blood test - saved his life; as such, he urged all men over 40 to discuss the PSA test with their doctors.  There is no doubt that the testimony of a high-profile individual such as Mr. Stiller will cause many men to consider getting a PSA test yet we at the American Council on Science and Health and many others have been critical of it, so it is fitting that we review where science stands on the issue.

The PSA is a blood test that measures...

A new study in the current JAMA Internal Medicine assessed the overall and specialty-specific response of our nation's doctors to the 2012 federal panel advisory against doing routine prostate-specific antigen testing.

In the study, coming in the form of a research letter, entitled...

A new study in the respected Journal of Clinical Oncology reports a significantly elevated risk among men treated with androgen deprivation therapy, or ADT, for advanced prostate cancer, and the subsequent development of Alzheimer's disease.

The goal of the ADT-type of hormone therapy is to lower the level of male sex hormones, or androgens, that would stimulate the growth of prostate cancer cells. The researchers were...

SupplementsBecause of the 1994 Dietary Supplement Health and Education Act (DSHEA), dietary supplement purveyors can't claim that their products can prevent, treat or cure disease. So they have to resort to "support" verbiage. But we know what they really mean.

Nowhere has this been more apparent than in the case of prostate cancer, as the number of products that purport to support prostate health are legion especially when it comes to prostate cancer. A recent study found, however, that support or not, such supplements don't do...

cancer cellsA report in the Journal of Urology details the cellular assessment of samples of prostate cancer tissue obtained on biopsies from 350 men in five U.S. medical centers. This retrospective analysis of the tissue samples was further compared to outcomes after repeat biopsies were obtained in all the study subjects within two years of the original biopsies, attempting to discern the predictive value of certain markers for recurrence or its absence.

The multicenter team was led by Dr. A. W. Partin of the James Buchanan Brady...

Examine your prostate?A large retrospective analysis of nearly 67,000 Medicare patients shows that there is no evidence that treating men with early-stage prostate cancer with androgen-deprivation therapy (ADT) is beneficial in terms of survival from the cancer itself, nor in terms of overall survival.

The new study appears in the current JAMA Internal Medicine, and was led by...

cancer cellsA report in the current JAMA on the rate of invasive cancers in America compared the rate of 2009 to 2010, and found room for optimism: the rate declined 3 percent over that one year (from 459 to 446 cases per 100,000). This is consistent with the trend of declining cancer rates overall which has largely tracked the decline in smoking rates over the past twenty-plus years.

1314902_99313658Just as women under the age of 50 are excessively screened for breast cancer using mammograms, frivolous prostate specific antigen (PSA) screening for men 75 or older goes against the grain, despite clinical guidelines suggesting otherwise.

Recent findings, published in JAMA, show 41 percent of about 61,000 men 75 or older routinely received PSA screening, with nearly 30 percent of the screenings ordered by their primary care physicians. In fact...

Examine your prostate?

Over the course of the past several years, some studies have shown that the drug finasteride (Proscar and Propecia), commonly prescribed to reduce prostate size or restore thinning hair, may also reduce the risk of prostate cancer. Now, a new review and update of prior studies published in today s New England Journal of Medicine supports this finding, although with...
