Prostate Cancer Screening Questioned
Government Panel Says Benefits Uncertain
"So, when you go back to fact that some men have prostate
cancers that will never cause them any harm and now you offer treatments that
have unpleasant side effects, men need to understand that going in," says
Brooks. "Men should talk about the benefits and limitations and understand
the pros and cons to make an informed decision."
Brooks says the report's findings now put the task force
largely in line with the recommendations of other major medical organizations,
including the American Cancer Society (ACS) and the American Urological
Association. The last time the task force looked at prostate cancer screening
in 1996, it recommended against it.
Those organizations and others currently recommend that doctors
offer annual prostate cancer screening to men over 50 and discuss the potential
risks and benefits.
"Men with a life expectancy of fewer than 10 years are
unlikely to benefit from screening even under favorable assumptions," write
the authors of the report, Russell Harris, MD, MPH, and Kathleen N. Lohr, PhD,
of the University of North Carolina at Chapel Hill and Research Triangle
Although not endorsed by the report, ACS also recommends annual
screening for men over age 45 who are at high risk for prostate cancer --
African-Americans or men with a brother or father who had prostate cancer.
While there is some indication that some dietary factors may
affect the risk of developing prostate cancer, Brooks says those claims have
not yet been proven and several studies are currently investigating new
prevention strategies for prostate cancer.
