In a recent Medical Fitness Network blog, Dr. James Fagelson discusses the findings from a recent Northwestern University study stating that metastatic (incurable) prostate cancer has increased by more than 90 percent in patients age 55-69 since 2004. This comes after a recommendation made in 2008 by the United States Preventive Services Task Force that advised doctors to cut back on PSA levels testing that evaluate levels of prostate-specific antigen that can indicate prostate cancer.
