We use data from the Behavioral Risk Factor Surveillance System between 2001 and 2010 to consider receipt of mammograms (breast cancer screening) among women ages 50 to 64 and pap smears (cervical cancer screening) among women aged 18 to 64. We use data from six New England states to estimate difference-in-difference models comparing changes in cancer screening in Massachusetts before and after health reform to changes in other New England states over the same period. Models control for individual covariates (age, marital status, education, employment, household income, and race) as well as state and year fixed effects. We also consider the effect among low-income women and racial and ethnic minority women. Preliminary results suggest a statistically significant effect of Massachusetts health reform on breast and cervical cancer screening. The effect is strongest for cervical cancer screening. For both breast and cervical cancer screening, the effect remains significant and is only slightly smaller in magnitude when controlling for individual health insurance coverage, suggesting the effect is driven largely by changes along the intensive margin (e.g. more generous or flexible health insurance coverage). Further, for both outcomes, the effect is stronger 2 to 3 years after the implementation of reform than in the years immediately following, suggesting the increase is not driven primarily by pent-up demand among the previously uninsured. Estimates from models limiting the sample to low-income or minority women are statistically insignificant for breast cancer screening, though positive and statistically significant for cervical cancer screening, with the largest effects among low-income women and smaller effects among minority women. Overall, Massachusetts reform appears to have increased breast and cervical cancer screening, particularly among low-income women, though the effect among minority women was not as large as among other groups.
