USPTF or all the others.....??? The updated ACOG guidelines agree with recommendations issued by the American College of Radiology (ACR), the Society of Breast Imaging, the American Cancer Society, and the American Society of Breast Disease. However, all of these differ from those of the United States Preventive Services Task Force (USPSTF). Mammography screening should be offered annually to women beginning at age 40 years, according to new breast cancer screening guidelines issued by ACOG. The new Practice Bulletin, entitled "Breast Cancer Screening," is published in the August 2011 issue of Obstetrics & Gynecology. These guidelines replace the 2003 ACOG recommendations, which were that women should have mammograms every 1 to 2 years beginning at age 40 years, and every year beginning at age 50 years. "Although women in their 40s have a lower overall incidence of breast cancer compared with older women, the window to detect tumors before they become symptomatic is shorter, on average," said guidelines coauthor Jennifer Griffin, MD, MPH, in a news release. "If women in their 40s have annual mammograms, there is a better chance of detecting and treating the cancer before it has time to spread than if they wait two years between mammograms."
