In order to explore the importance of PA for the outcome after a surgical procedure due to gallbladder disease, breast cancer and colorectal cancer we will ask all patients operated for any of the three above mentioned conditions to answer a short questionnaire (Appendix I) including the Saltin and Grimby (7) questions to study of the effects of the level of PA immediately before surgical operations. The patients will be asked to estimate their physical activity four weeks prior to the surgical procedure.
