Exercise During Chemotherapy Improves Quality of Life for Breast Cancer Patients

For women undergoing chemotherapy for breast cancer, maintaining quality of life can be a significant challenge. Fatigue, emotional strain, and loss of muscle mass are common obstacles. However, a latest study reveals that incorporating exercise into a chemotherapy regimen measurably improves physical, emotional, and mental well-being, helping patients navigate this demanding period with greater resilience.

The research, led by investigators at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, is a meta-analysis published in The Lancet Healthy Longevity. It synthesizes data from over two dozen studies involving women receiving chemotherapy for breast cancer.

The Importance of Quality of Life During Treatment

Even as advancements in breast cancer treatment have dramatically improved survival rates, clinicians and researchers are increasingly focused on the patient experience during treatment. “Quality of life becomes a central outcome during treatment, not something to consider only after it ends,” explains LaShae D. Rolle, MPH, CPH, lead author of the study and a predoctoral fellow at Sylvester.

Chemotherapy impacts the entire body, making quality of life a crucial factor. Historically, exercise was primarily recommended after cancer treatment. However, uncertainty remained regarding its benefits during chemotherapy itself.

Study Findings: Exercise Makes a Difference

The Sylvester-led team analyzed 21 randomized controlled trials, encompassing more than 3,000 women undergoing chemotherapy for breast cancer. The analysis considered a variety of exercise interventions, including:

• Aerobic activity (walking, cycling)
• Strength or resistance training
• Combined programs

Women who participated in structured exercise programs experienced significant improvements in quality of life compared to those receiving standard care alone. These benefits spanned physical, emotional, and mental health domains.

“It’s not about pushing through exhaustion,” Rolle emphasizes. “It’s about finding movement that supports the body while it’s under strain.”

No One-Size-Fits-All Approach

Importantly, the study found that no single type of exercise was superior. Aerobic exercise, strength training, and combined programs all yielded meaningful improvements. This flexibility is particularly valuable during chemotherapy, when energy levels can fluctuate.

“Exercise during treatment shouldn’t feel rigid or intimidating,” says Tracy Crane, Ph.D., RDN, co-author of the study, co-leader of the Cancer Control Program, and director of lifestyle medicine, prevention, and digital health at Sylvester, and associate professor in the Division of Medical Oncology at the Miller School. “This study reinforces that patients can benefit from many different forms of movement, as long as the approach is safe, personalized, and realistic.”

Focus on Active Chemotherapy Patients

The study specifically focused on women undergoing active chemotherapy, distinguishing it from research on cancer survivors. This distinction is important because exercising during chemotherapy presents unique challenges related to symptoms, treatment schedules, and physical capacity. The findings align with existing clinical guidelines that encourage physical activity during treatment, with appropriate supervision and adjustments.

“This evidence gives clinicians greater confidence to recommend exercise during chemotherapy,” Rolle states. “And it reassures patients that movement, at the right level, can be part of their care.”

Integrating Exercise into Oncology Care

As cancer care evolves, integrating supportive strategies like exercise alongside medical treatment is becoming increasingly important. “This work helps move exercise from the margins into the mainstream of oncology care,” Crane concludes. “It shows that any form of exercise during chemotherapy has a positive impact on quality of life for women being treated for breast cancer.”
