title: Effects of exercise interventions and physical activity behavior on cancer-related cognitive impairments: an update.
abstract: The purpose of this review is to give an update on studies investigating the influence of physical activity behavior and exercise interventions on cancer-related cognitive impairments.
  
  
  
  Cross-sectional and observational studies underline previous findings, revealing an association of cancer patients' fitness and their cognitive functions. Results from interventional studies are sparse. Only one study investigated self-perceived cognitive function in breast cancer patients as a secondary outcome, indicating no effects.
  
  
  
  Recent research on physical activity and exercise interventions is still restricted by methodological limitations, including the wide variation in assessments and the lack of adequate control groups.
