Effects of Physical Activity in Early Stage Hormone Receptor Positive Breast Cancer Patients

This study is looking at how a structured physical activity program can improve the quality of life for women recovering from breast cancer. Researchers want to see if regular exercise helps survivors manage the side effects of long-term hormone therapy and improves their overall well-being. This is an observational study, which means the researchers will monitor your progress while you participate in a specific 12-week exercise program called "Medicina and Sport," organized by the ANDOS association.

To be eligible for this study, you must be a woman at least 18 years old with stage I, II, or IIIa hormone receptor-positive breast cancer. You must currently be taking hormone therapy (endocrine therapy) to help prevent the cancer from returning. This trial is not for patients who are currently receiving chemotherapy, those with metastatic (stage IV) cancer, or those with a history of serious heart disease or bone fractures in the spine or hip. Because the study focuses on physical movement, you should talk to your doctor about your current fitness level and whether you have any health conditions that might make exercise difficult. You should also discuss how the 12-week schedule fits with your current follow-up care and what specific quality-of-life symptoms, such as fatigue or joint pain, you hope to improve through increased activity.
