Low Breast Density In Mammography Can Worsen Breast Cancer Prognosis

Low Breast Density In Mammography Can Worsen Breast Cancer Prognosis
shutterstock_168167666A recent study from the University of Eastern Finland concluded that very low mammographic breast density significantly worsens breast cancer's prognosis. The authors show that disease free survival and the general life expectancy were much shorter in women who had very low breast density when compared to those with high density breasts. The observations support the observation that reduced density of breast tissue corresponds to lower amounts of fibroglandular tissue versus fat tissue. These findings might prove significant in the evaluation of breast cancer treatment approaches and prognosis. In this study, 270 patients (between 32 and 86 years of age) with breast cancer registered at the Kuopio University Hospital were studied. The density of breast tissue was analyzed through mammographic images obtained when diagnosis was revealed. Researchers calculated the amount and proportion of dense glandular tissue within the total breast area. The density of breast tissue was divided in two categories: low (when the proportion of glandular tissue was under 25 percent) and very low (when the proportion of glandular tissue was under 10 percent).
