Mammography is a screening procedure that has decreased the risk of death from breast
cancer by 25% to 30%, as shown in 7 randomized studies (Table
1).1-8 It can detect breast
cancer or carcinoma in situ at 5 to 10 mm in diameter. Most physicians
cannot reliably detect lesions smaller than 10 mm on physical
examination, and patients generally seek medical attention for lesions
that are 25 mm or larger.
