Breast cancer risk characteristics of women undergoing whole-breast ultrasound screening versus mammography alone.
This study evaluated mammography screening failure risk among women undergoing supplemental ultrasound screening in clinical practice in comparison with women undergoing mammography alone. Screening ultrasounds and screening mammograms without supplemental screening were identified within three Breast Cancer Surveillance Consortium registries. A clinically significant proportion of women who had undergone mammography screening alone were at high mammography screening failure risk. Ultrasound screening was highly targeted to women with dense breasts, but only a small proportion were high mammography screening failure risk.

Variation in second breast cancer risk after primary invasive cancer by time since primary cancer diagnosis and estrogen receptor status.
This study examined the timing of second breast cancers by primary cancer estrogen receptor (ER) status in the Breast Cancer Surveillance Consortium. The cohort studied included women who were diagnosed with American Joint Commission on Cancer stage I-III breast cancer identified within six Breast Cancer Surveillance Consortium registries from 2000 to 2017. Characteristics collected during primary breast cancer diagnosis included demographics, ER status, and treatment. Second breast cancer events included subsequent ipsilateral or contralateral breast cancers diagnosed >6 months after primary diagnosis. Cumulative incidence and second breast cancer rates by primary cancer ER status during 1-5 versus 6-10 years after diagnosis was examined. At 10 years, the cumulative second breast cancer incidence was 11.8% for women with ER-negative disease and 7.5% for those with ER-positive disease. Women with ER-negative cancer had higher second breast cancer rates than those with ER-positive cancer during the first 5 years of follow-up. After 5 years, second breast cancer rates were similar for women with ER-negative versus ER-positive breast cancer.

Using protection motivation theory to predict intentions for breast cancer risk management: intervention mechanisms from a randomized controlled trial.
The objective of this study was to evaluate direct and indirect effects of a web-based, Protection Motivation Theory (PMT)-informed education and decision support tool for risk-reducing medication and breast MRI among women with high risk of breast cancer. Findings indicated that PMT-informed intervention effected behavioral intentions. No direct intervention effect on intentions for risk-reducing medication or MRI were found, but there were significant indirect effects on risk-reducing medication intentions via perceived risk, self-efficacy, and response efficacy, and on MRI intentions via perceived risk and response efficacy, The authors suggested that future research should extend these findings from intentions to behavior.
