ASSESSMENT OF THE RADIOLOGICAL RISK FOR CANCER INCIDENCE AND MORTALITY IN DBT (DIGITAL BREAST TOMOSYNTHESIS) USING STATE-OF-THE-ART RISK MODELS AND MONTE CARLO SIMULATIONS

In this study it has been shown that no significant increase of dose arises from the use of DBT when compared to Digital Mammography. Regarding the radiological cancer risk,the lung, after the target organ (breast), is the organ more exposed and that presents a higher risk of cáncer incidence with respect to the other organs.

Lung cancer incidence as a function of the age at exposure, when a CC DBT examination is performed, computed for two monochromatic energies: 20 keV and 28 keV. The dose absorbed by the lungs is normalized to the 4 mGy absorbed dose in the breast. Straight line represents interpolated data.
