How often do I need a mammogram?

Question

Accepted Answer

The mammogram schedule for average-risk women, per NCI's screening guidance: screening runs from 40 through 74, every one to two years - the major US guidelines landed on starting at 40, with annual or biennial intervals both supported, and yearly common between 40 and 54. After 74, the decision is individual, based on health and life expectancy.

The high-risk track is different and worth knowing: a first-degree relative with breast or ovarian cancer, a known BRCA mutation, chest radiation in youth, or a personal history - these move screening earlier, often to 30 or ten years before the youngest family case, and usually add MRI to the mammogram. If that is your history, it is a formal risk assessment conversation, not a default schedule.

Practical notes: a callback after a first mammogram is common and usually means more pictures, not cancer - first scans have no baseline for comparison. Dense breasts, common in younger women, make mammograms harder to read and slightly raise risk - many states now notify you of density, and supplemental ultrasound or MRI is the follow-up conversation. Report new lumps between mammograms promptly rather than waiting for the schedule - screening is for people without symptoms.
