Mr. Julian Marshall: Technical Feasibility of Assessing Breast Density

Breast density is among the factors believed to be a strong predictor of future breast cancer risk. Current radiology practice for assessing density involves humans looking at films and gauging proportions of “whiteness”. The shift to digital mammography makes the assessment more difficult since digital mammography image processing suppresses the visual appearance of density. Whereas human assessment produces breast compositions by rough category, automated methods will provide a continuum of breast density values. It is the latter that would be more appropriate for inclusion in risk models.
