What percentage decrease in mortality results from regular screening in clients above 50?
About 30%.
There is the "Mappa Mundi" of DCIS - the calcifications are "wild and crazy", there are X's, Y's and Z's visible haphazardly distributed on a segment of the breast. Look carefully at the distribution; you can see the calcifications in a ductal distribution as the DCIS grows out of blood supply and calcifies in response.
