Correct answer: B — Start at 40; biennial 40-74
For an average-risk 46-year-old woman, the current USPSTF recommendation is to perform screening mammography every 2 years from age 40 through 74 years. This is a change from the older approach of routinely starting at 50. Dense breasts alone do not create a USPSTF recommendation to start at 35 or to add routine supplemental ultrasound/MRI after a normal mammogram; evidence is considered insufficient for supplemental screening based solely on breast density. Therefore, the correct answer is B: start at 40; biennial screening from 40 to 74.
