A groundbreaking study conducted by the Helen F. Graham Cancer Center & Research Institute at ChristianaCare has shed light on how exercise can effectively reduce pain and improve quality of life for women with breast cancer undergoing treatment with aromatase inhibitors (AIs). The research compared a directed stretching regimen with walking, revealing that targeted exercises significantly alleviated joint stiffness and pain—common side effects of AIs.
This article explores the study’s findings, its implications for breast cancer treatment, and how exercise is empowering patients to improve their well-being.
The Study’s Focus: Reducing Pain from Aromatase Inhibitors
Aromatase inhibitors, commonly prescribed for women with estrogen receptor-positive breast cancer, are pivotal in reducing cancer recurrence. However, joint pain and stiffness caused by AIs often lead to noncompliance, with up to 50% of patients reducing or stopping their medication.
The study, titled “Directed Exercise Intervention in Breast Cancer Patients with Arthralgias Receiving Aromatase Inhibitors,” involved 27 women split into two groups: one engaging in daily stretching exercises and another participating in a walking regimen. Results demonstrated that the stretching program was more effective in reducing joint pain and improving mobility, providing hope for women struggling with AI side effects.

The Directed Exercise Program
The exercise regimen, developed in collaboration with rehabilitation specialists, included 15 minutes of daily stretching and joint mobility exercises over an eight-week period. Key activities targeted areas such as hamstrings, quadriceps, calf muscles, and hand strength, addressing the most commonly affected joints.
Women who participated in the program reported improvements in grip strength, reduced pain, and better overall mobility. For participants like Sarah Erhart, the program empowered them to reclaim their physical strength, describing it as a way to “fight back” against the challenges of cancer treatment.
A Global Impact: Spreading the Benefits
The study’s success has garnered attention beyond the research center. Pharmaceutical giant Pfizer plans to distribute the exercise regimen globally as part of its education program for physicians prescribing AIs. This initiative is expected to benefit thousands of women worldwide, enhancing compliance with lifesaving treatments by mitigating painful side effects.
This approach highlights the importance of integrating non-pharmaceutical interventions into cancer care, showcasing the potential of exercise as a cost-effective, accessible, and empowering tool.

Empowering Patients Through Movement
For many participants, the study was a transformative experience. Pat DiIenno, a control group member, shared that simply being part of the research motivated her to incorporate more movement into her routine, leading to noticeable improvements in her joint pain. This highlights how even minimal changes in physical activity can yield significant benefits for cancer patients.
Additionally, participants noted that the exercises offered a sense of control during a challenging time. By focusing on physical wellness, they felt more equipped to handle the side effects of treatment, boosting both their physical and emotional resilience.
Looking Ahead: Integrating Exercise into Cancer Care
The ChristianaCare study underscores the potential of exercise to revolutionize cancer care by addressing treatment side effects and improving quality of life. For women undergoing AI therapy, this research offers a pathway to better outcomes through simple, targeted interventions.
In conclusion, exercise is proving to be a vital component of cancer treatment, offering a drug-free solution to manage pain and support long-term health. Studies like this pave the way for a more holistic approach to care, empowering patients to take an active role in their recovery journey.
