Abstract: We evaluated deficit accumulation and how deficits affected cognition and physical activity among breast cancer survivors and non-cancer controls.

Aknowlegement: We are also indebted to Sherri Stahl, Naomi Greenwood, Margery London, and Sue Winarsky, who serve as patient advocates from the Georgetown Breast Cancer Advocates, for their insights and suggestions on study design and methods to recruit and retain participants.
