1 If two consecutive transfusions yield increments that do not meet the minimum standard for a successful transfusion (see Refractoriness below), the effectiveness of subsequent platelet transfusions should be evaluated by performing a count 10 to 60 minutes after their completion.
American College of Radiology: Starting at 40, get a mammogram every year. American College of Gynecology and Obstetrics: At 40 to 49, get a mammogram every year or every two years; at 50 and older, a mammogram every year.

Screening mammograms are one of the best ways to diagnose breast cancer early, when it's most treatable. A large study confirmed the benefits of regular mammograms. This study also emphasized that there is no upper age limit for mammograms. More than 12,000 women age 80 or older participated in this study. Of the women diagnosed with breast cancer, those who had regular mammograms (at least three mammograms in the 5 years before being diagnosed) were more likely to be diagnosed with early-stage disease.
