Feasibility Study: Yoga Educational Project

As much as 45 to 60% of patients treated with hormonotherapy (HT) for breast cancer (BC) suffer from osteoarticular pain during treatment. Secondary effects have become a real issue because of their consequences on the patients\' quality of life, but also on treatment efficacy and survival when they induce dose reduction or premature withdrawal of treatment. Additional medicines (acupuncture, hypnosis, yoga) have become more and more popular these last years. 48 to 80% of patients with BC eventually choose them. A review comparing efficacy of various therapies to decrease osteoarticular pain concludes to a highest efficacy of anti-inflammatory treatments, paracetamol and yoga. With this project, the investigators will assess the feasibility of a therapeutic yoga program with home practice for patients with breast cancer treated with hormonotherapy. The investigators will measure adhesion of the patients to perform yoga postures in an autonomous manner. Our study will also allow collection of data on the effect of such a program on quality of life, in view of setting-up an intervention study.
