['Although many survivors continue to worry about cancer years after completing treatment, little is known about factors associated with cancer worry. This study examined associations between breast cancer worry and demographic and clinical variables, as well as fatigue, symptom burden, and risk perception in a sample of breast cancer survivors 3\u2009years post-adjuvant treatment. We hypothesized that after controlling for demographic and treatment factors, a significant proportion of variance in cancer worry would be explained by greater fatigue severity, more symptom burden, and greater perceived risk of recurrence.', "Stage 0-II breast cancer patients (N\u2009=\u2009202) completed measures of risk perception, cancer worry (modified Lerman's Cancer Worry Scale), symptom burden (Memorial Symptom Assessment Scale), and fatigue severity (Fatigue Symptom Inventory) 3\u2009years after completing adjuvant treatment. Multiple regression analyses were used to determine the proportion of variance in cancer worry accounted for by fatigue, symptom burden, and risk perception after controlling for demographic and clinical variables.", 'Age, fatigue, symptom burden, and risk perception each explained a significant proportion of variance in cancer worry (p\u2009<\u20090.05). Fatigue, symptom burden, and risk perception together accounted for 27% of the variance in cancer worry after controlling for demographic and clinical factors (p\u2009<\u20090.01).'] Do factors associated with breast cancer worry 3 years after completion of adjuvant treatment?
