May 30, 2012 - A national medical panel advises against men using the Prostate-Specific Antigen test for cancer screening. The US Preventive Services Task Force has announced its final recommendations. The task force is a panel of doctors who advise the government on cancer screenings and other ways to avoid disease. The panel found the PSA blood test unreliable, resulting in too many false positives. The test measures a protein called prostate specific antigen. The task force says the test often leads to unnecessary needle biopsies for men who don't actually have cancer. According to the American Cancer Society, prostate cancer is the second deadliest cancer among men, and occurs most often in African American men.
Also, according to researchers in St. Louis, folic acid may reduce some childhood cancers, especially kidney cancer and brain tumors. A new study shows Folic acid fortification of foods may reduce the incidence of the most common type of kidney cancer and a type of brain tumors in children. Since 1998, the U.S. Food and Drug Administration has mandated fortification of foods with folic acid because earlier studies show that prenatal consumption of folic acid significantly reduces the incidence of neural tube defects in babies. The study is published in the current issue of Pediatrics
