SAN DIEGO--Women between the ages of 40 and 49 must still decide for themselves if undergoing a mammography is appropriate for them, according to a panel of experts at the American College of Physicians (ACP) Annual Session. The inability of key organizations to come to a decisive conclusion is the result of conflicting studies and the fact that "each organization espouses different rules of evidence," said Mary E. Costanza, MD, professor of medicine, University of Massachusetts Medical School.
