...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...
...research moves into a digital age and resources become increasingly available online, the natural assumption might be that the library and librarians are losing their relevance.
