...doctors' most powerful tools against breast cancer. There is a robust body of clinical-trial evidence showing that routine screening reduces breast-cancer deaths; the task force attests to that as well. But while everybody, to varying extent, agrees that mammograms are beneficial, what's less clear is the age at which routine mammography screening should begin. That depends in part on breast cancer risk, which increases with age - for every 100,000 women, the risk of developing breast cancer is 1 in 69 in women in their 40s, 1 in 38 in women in their...
Overall, based on a review of mammography trials, the panel found that having a yearly mammogram screening cuts the risk of breast-cancer death 15% in women ages 40 to 49. That reduction, it should be noted, is relative, not absolute. The absolute risk of breast-cancer death after age 40 is 3% without annual screening, according to the computer models. That means that with routine screening, which leads to a 15% lower risk of death from breast cancer, a woman's absolute risk drops to 2.6%. Small numbers in either case. Put another way, the panel concluded, the benefit...
That benefit increases, however, with the age of the women being screened, as the risk of breast cancer rises: among women 50 to 59, one death is averted for every 1,339 women routinely screened; among women 60 to 69, 377 mammograms would be needed to prevent one death. The task force's computer models further showed that shifting women's screening schedule from yearly to once every two years retains 81% of the benefit of screening while reducing the harms like false positives by half...
