396 – Breast cancer screening: understanding risk, deciding when to start, and more
Peter Attia explains why 42,000 women still die from breast cancer each year and lays out a personalized, risk-based screening framework to catch cancers earlier.
The gist
-
Attia says to complete a risk assessment by age 25 using validated calculators, since family history and genetics can shift your screening timeline forward by a decade.
-
For average-risk women, Attia recommends annual 3D mammography starting at 40, which saves 230 life-years per 1,000 women versus 165 for every-two-years screening.
-
High-risk women or those with dense breasts should add MRI to their routine, as Attia says it cuts interval cancer rates in half despite being widely underused.
-
Attia says to seek high-volume, specialized breast imaging centers because radiologist expertise directly affects how well cancers are detected.
