Cancer survivors who participated in a four-week yoga program experienced significant improvements in sleep quality, reduced fatigue and lower anxiety levels, according to a new randomized trial presented at the 2026 American Society of Clinical Oncology Annual Meeting in Chicago last week. The research, led by the University of Rochester Medical Center, offers hope for patients seeking drug-free options to manage common cancer treatment side effects.
The study involved 410 adult cancer survivors across multiple community cancer care sites in the United States. Participants who completed the yoga program showed moderate-to-large reductions in mood disturbances and medium-to-large reductions in fatigue, with no major safety concerns or serious adverse events reported during the trial.
Main Developments From the Clinical Trial
The research team, led by Yuri Choi, PhD, from the Wilmot Cancer Institute at the University of Rochester Medical Center, tested a specialized program called YOCAS, which stands for Yoga for Cancer Survivors. The program required participants to attend two instructor-led 75-minute yoga sessions each week for four weeks.
Each session incorporated 18 different poses from Gentle Hatha yoga and Restorative yoga styles, combined with breathing exercises and mindfulness training. The combination was specifically designed to address the unique physical and emotional challenges faced by cancer survivors.
Results showed that participants in the yoga group experienced small-to-medium reductions in anxiety alongside the improvements in sleep and fatigue. The findings suggest that a single intervention could address multiple quality-of-life concerns that cancer survivors commonly face after treatment.
“This indicates that cancer survivors have an option to alleviate these cancer-related side effects at the same time, without adding another drug,” Choi said regarding the study findings.
What We Know So Far
The clinical trial enrolled 410 adult cancer survivors with an average age of 54 years. The participant population was predominantly female, with 96 percent of participants being women. Breast cancer survivors made up 75 percent of the study group, while 93 percent of participants identified as Caucasian. Additionally, 82 percent had some college education or higher.
The study was funded by the National Cancer Institute and conducted at multiple community cancer care sites throughout the United States. Researchers noted that no serious adverse events related to the yoga practice were observed during the four-week program.
However, the research team acknowledged important limitations. The study excluded patients with metastatic cancer, and the findings have not yet undergone peer review. Choi noted the homogeneity of the study population as a factor that could limit broader application of the results.
“The sample in our clinical trial was relatively homogeneous, with most participants being women (96%), breast cancer patients (75%), Caucasian (93%), and having some college or higher education (82%),” Choi explained.
What Happens Next
The research team is working to make the yoga intervention more accessible to a wider range of cancer patients and survivors. Efforts are underway to adapt the program to reach underserved populations and those in geographically isolated areas.
“We are adapting our intervention to reach all cancer patients and survivors, including the creation of a mobile app to reach people in rural communities,” Choi stated.
The study results are considered preliminary until they undergo peer review. Additional research will be needed to determine whether the benefits observed during the four-week program persist over longer periods and whether similar results can be achieved in more diverse populations, including patients with different cancer types, racial and ethnic backgrounds, and education levels.
Important Details for Cancer Survivors Considering Yoga
The YOCAS program specifically used Gentle Hatha and Restorative yoga styles, which are designed to be accessible for people dealing with health challenges. The 75-minute sessions twice weekly provided structure while remaining manageable for participants who may be dealing with treatment-related fatigue.
For cancer survivors interested in trying yoga, the researchers offered practical guidance on finding appropriate instruction. Safety and proper guidance were emphasized as key considerations when selecting a yoga practice.
“Survivors should also look for certified yoga instructors who have experience working with cancer patients/survivors or individuals with other challenging health conditions. They should not be afraid to ask their oncology team for referrals to qualified instructors in their community,” Choi advised.
The study measured several specific outcomes including insomnia severity, fatigue levels, anxiety and overall mood disturbance. While the specific statistical values were not detailed in the presentation, the research team characterized the improvements as ranging from small-to-medium for anxiety to medium-to-large for fatigue and moderate-to-large for mood disturbances.
Study Limitations and Considerations
Cancer survivors and healthcare providers should consider several factors when evaluating these findings. The research has not yet been peer-reviewed, which means it has not undergone the standard scientific vetting process that typically precedes publication in medical journals.
The study population was notably homogeneous, which limits the ability to generalize results to all cancer survivors. Results for men, non-breast cancer survivors, non-Caucasian populations, and those with less formal education may differ from what was observed in this trial.
Patients with metastatic cancer were not included in this research, so the safety and effectiveness of this yoga program for that population remains unknown. Cancer survivors should consult with their oncology team before beginning any new exercise program.
The research does not provide information about whether the sleep, fatigue and anxiety improvements continue beyond the four-week program period. Long-term benefits have not been established through this study.
Frequently Asked Questions
What type of yoga was used in the cancer survivor study?
The study used a program called YOCAS featuring 18 poses from Gentle Hatha and Restorative yoga styles, combined with breathing exercises and mindfulness training. Sessions were 75 minutes long and held twice weekly for four weeks.
Who can benefit from yoga for cancer survivors?
This study included adults with an average age of 54. Participants were primarily breast cancer survivors who had completed treatment. The research excluded patients with metastatic cancer. Cancer survivors should consult their oncology team before starting yoga.
How do I find a qualified yoga instructor for cancer survivors?
Researchers recommend looking for certified yoga instructors with experience working with cancer patients or individuals with challenging health conditions. Patients can ask their oncology team for referrals to qualified instructors in their community.
Is yoga safe for cancer survivors?
The study reported no major safety concerns or serious adverse events related to the yoga practice among the 410 participants. However, the research specifically used gentle styles of yoga and included only non-metastatic cancer patients. Individual safety may vary.
Were the study results peer-reviewed?
The findings were presented at the 2026 ASCO Annual Meeting but have not yet been peer-reviewed. This means the research has not undergone the standard scientific review process that precedes publication in medical journals.
The research adds to growing evidence that complementary approaches may help cancer survivors manage treatment side effects. Cancer survivors interested in yoga should discuss options with their healthcare providers and seek instructors experienced in working with patients facing health challenges.
