Breast cancer disparity equally impacted by social determinants of health, tumor biology
University of Illinois ChicagoResearchers calculated the effect of social determinants of health — specifically neighborhood disadvantage and insurance status — on mortality and found they accounted for 19% of the disparity. They also calculated the effect of biological characteristics of the tumors by looking at data from genomic laboratory test results, which were used to anticipate tumor response to chemotherapy and likelihood of recurrence. They found tumor biology accounted for 20% of the disparity.
