Purpose Physical activity (PA) during and after cancer treatment is associated with improved cancer- and non-cancer-related outcomes. We assessed for predictors of change in PA levels among cancer survivors. Methods Adult cancer survivors from a comprehensive cancer center completed a one-time questionnaire retrospectively assessing PA levels before, during, and after cancer treatment along with their perceptions of PA. Multivariable logistic regression models evaluated the association of clinico-demographics variables and perceptions of PAwith changes in whether patients were meeting PA guidelines after cancer diagnosis. Results Among the 1003 patients, 319 (32%) met moderate to vigorous PA (MVPA) guidelines before diagnosis. Among those meeting guidelines before diagnosis, 50% still met guidelines after treatment; 12% not meeting MVPA guidelines initially met them after treatment/at follow-up. Among patients meeting guidelines before diagnosis, better ECOG performance status at follow-up, receiving curative therapy, and spending a longer time on PA initially were each associated with meeting guidelines at follow-up. After controlling for other variables, perceiving that PA improves quality of life (adjusted odds ratio, aOR = 11.09, 95%CI [1.42–86.64], P = 0.02) and overall survival (aOR = 8.52, 95%CI [1.12–64.71], P = 0.04) was each associated with meeting MVPA guidelines during/after treatment, in patients who
