Therapeutic Education and Nursing Support Program for Supportive Care, in Patients Treated With Hormone Therapy for Non-metastatic Breast Cancer

This French study is testing whether a structured nursing education and support program can help women with non-metastatic breast cancer better manage the side effects of hormone therapy (such as anti-estrogens or aromatase inhibitors). These medications are effective but often cause side effects that lead women to stop taking them. Better support may improve adherence and quality of life. **You may be eligible if...** - You are a woman between 18 and 75 years old - You have non-metastatic breast cancer and your treatment team has recommended adjuvant hormone therapy - Your overall health is reasonably good (ECOG ≤2) - You can read and understand French - You have internet access for online questionnaires **You may NOT be eligible if...** - You have metastatic (stage IV) breast cancer - You do not understand French - You do not have internet access - You are under 18 or over 75 Talk to your doctor to see if this trial is right for you.
