Mammography & tomosynthesis

Low-dose breast X-ray used for screening. Newer 3D versions find more cancers with fewer false alarms.

Population mammographic screening reduces breast cancer mortality by roughly 20% in screened women. Digital breast tomosynthesis (3D) improves detection in dense breasts. Contrast-enhanced mammography approaches MRI sensitivity at lower cost. AI reading (Transpara, Lunit, Mirai risk model) is being deployed at scale in Europe.

How it works

Low-energy X-rays compress and image the breast; tomosynthesis acquires multiple angles and reconstructs slices.

Strengths
  • Proven mortality benefit
  • Cheap and scalable
Limitations
  • Reduced sensitivity in dense breasts
  • Overdiagnosis of indolent lesions

MASAI: AI-supported mammography screening finds more cancers with half the radiologist workload

AI can take over one reader's work in double-reading screening programmes while finding more cancers. Whether the extra cancers found are ones that would have harmed women, and whether interval cancers fall, is the question the trial's primary endpoint will answer.
