First seen Jun 26, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This study tests whether doing Pilates exercises three times a week for 12 weeks can improve bone density in breast cancer survivors aged 40-60 who are taking hormone therapy (aromatase inhibitors). These women are at higher risk for bone loss and osteoporosis. The trial will measure changes in bone mineral density and quality of life in 60 participants.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pilates exercises
- What this could lead to
- If it works, this could offer a simple, drug-free way to help breast cancer survivors maintain bone strength while on hormone therapy.
- What could go wrong
- This is a small, early-stage trial with only 60 participants over 12 weeks. Bone changes may be too small to matter, and results may not apply to all survivors.

Inclusion Criteria: 1. Female breast cancer survivors aged 40-60 years. 2. Histologically confirmed stage I-III breast cancer. 3. Currently receiving hormonal therapy (aromatase inhibitors) for at least 3 months. 4. At risk of osteoporosis or with low bone mineral density (BMD) defined by T-score ≤ -1.0 at lumbar spine or hip. 5. Medically cleared for exercise, specifically low-to-moderate intensity Pilates. 6. Able to attend supervised exercise sessions three times per week for 12 weeks. 7. Willing and able to provide written informed consent. Exclusion Criteria: 1. Metastatic (stage IV) or recurrent breast cancer. 2. History of osteoporotic fractures in the past 12 months. 3. Severe cardiovascular, respiratory, or musculoskeletal conditions that contraindicate exercise. 4. Uncontrolled hypertension, diabetes, or thyroid disorders. 5. Current use of corticosteroids. 6. Active bone metabolic disease other than osteoporosis (e.g., Paget's disease, osteomalacia). 7. Severe cognitive impairment or psychiatric illness preventing adherence to exercise or supplementation. 8. Known allergy or intolerance to calcium or vitamin D supplementation. 9. Participation in another clinical trial with structured exercise or bone-targeted intervention within the last 3 months.
