We
have demonstrated the feasibility of investigating the reduction of density
following chemotherapy using a quantitative analysis method based on MRI.
Patients receiving chemotherapy showed reduction of breast density, and that
the effects were more pronounced in younger women than older
(post-menopausal) women. The results suggest that the reduction of breast
density after chemotherapy was possibly mediated through impaired ovarian
function. The reduction could be clearly noted after 1 to 2 cycles of AC
regimen. Although the density continued to decrease after 4 cycles of AC and
the following Taxane regimen, the subsequent effect was smaller.
