Breast imaging is a subspecialty of diagnostic radiology. It involves a range of imaging procedures.
Screening mammography is used to detect breast cancer via a low-dose X-ray before any symptoms are evident.
Breast tomosynthesis is a new digital mammography technique that produces 3D images of the breast using X-rays. Diagnostic mammography uses X-rays for diagnostic purposes when symptoms are present.
The mammogram confirms whether the changes are non-cancerous (benign) or whether breast cancer may be present and treatment is required.
