Standard mammographic views

A routine mammogram includes two views of each breast

–     Craniocaudal (CC) and

–     Mediolateral oblique (MLO)

Obtaining 2 views from each breast improves cancer detection (11-25% would be missed with only 1 view) and helps differentiate superimposed tissue from a real finding and thus reduces recall rates; but increases cost and radiation exposure (radiation from routine 2-view mammogram = 3 months of natural background radiation)
