Descriptive Observational Study of the Evolution of the Lifestyle Alteration in Patients With Breast Cancer

Scientific context: With more than one million cases per year, breast cancer is the most common female cancer. All treatments such as surgery, chemotherapy, radiotherapy or hormone therapy lead to major changes patients' lifestyle. These treatments can lead to a decrease of physical activity due to fatigue and also changes in the diet. Sometimes, chemotherapy induces nutritional aversions and can cause weight gain that is known to increase the risk of recurrence. Cognitive complaints are also frequent, in particular in patients who received chemotherapy and can also lead to quality of life's alteration Fatigue assessed with prevalence between 70 % and 100 % is usually a part of a series of symptoms including anxiety, depression, pain, sleep disturbance, decreased activity level, nutritional changes and pre-existent comorbidities. These symptoms can lead to an alteration of the quality of life. The chemotherapy involves disturbances at physiological, psychological and social levels and eating disorders leading to changes in eating habits which can lead to weight loss or weight gain. To limit these deleterious changes in lifestyle, increased physical activity, specialized counseling and nutritional monitoring may be recommended. According to current knowledge there is no prospective study that evaluated different lifestyle changes according to different types of patients and the appearance of the installation of these symptoms during the patient pathway. Research hypothesis: the study hypothesis is that description of the evolution of the quality of life and, physical, nutritional and cognitive parameters in a population of patients with non-metastatic breast cancer will better characterize these patients in order to propose an appropriate and personalized rehabilitation intervention.The investigators propose this feasibility study consisting of 2 cohorts of patients according to the adjuvant therapy given (+/- chemotherapy) after the primary breast surgery.
