About this study

REBECCA-1 is an observational study. Clinical research is undergoing a revolutionary change. The use of electronic patient records (EHR), digital registers, smartphones etc will create "real-world data" (RWD) that provides great opportunities for advancing clinical research, but so far this opportunity has been little exploited. The REBECCA -1 study will observe and monitor fatigue in breast cancer survivors. Investigators will use self reported questionnaires (PROM-data), blood tests and objective regulations like the REBECCCA -1 smart watch that will register amount of steps every day, leaving the house, visiting friends, cafes etc. There will be three observational arms; 1.high fatigue, 2. low fatigue and 3. a healthy control arm. After the patients have finished their treatment, they will receive the REBECCA smart watch, a REBECCA app on the smart phone and a REBECCA plus device on their computer, The next offend are also invited to report their evaluation through the same apps. The observational time will be 1 year and comparison between the subjective PROM data , the objective REBECCA watch and the biological samples will be obtained.
