Facing advanced breast cancer can feel like an overwhelming battle, but what if there was a way to fortify your body and improve your quality of life during treatment? A recent clinical trial has uncovered some encouraging news: exercise can significantly benefit women battling advanced breast cancer.
The study focused on the impact of exercise on women with advanced breast cancer, specifically stage 4, a stage where the cancer has spread beyond the breast. The results are promising, showing that regular exercise can help these women better withstand both the harsh treatments and the debilitating effects of the disease.
The trial involved a nine-month program incorporating supervised aerobic and resistance exercises. Participants experienced notable improvements in muscle mass and strength, especially in their arms and legs. Within the first three months, women in the exercise group gained nearly 2 pounds of muscle mass compared to a control group.
Even as time passed, and some muscle mass was lost, the women in the exercise group still retained almost 1 pound more muscle than the control group after six months. This is crucial because maintaining muscle mass is linked to better treatment tolerance and overall health.
"The results from our study are important since lean body mass is linked to better treatment tolerance, prognosis and overall health, and increased muscle strength correlates with improved quality of life and lower mortality risk," said researcher Anne May.
The study included 357 patients with stage 4 breast cancer from hospitals in Germany, Poland, Spain, Sweden, and The Netherlands between 2019 and 2022. The exercise program consisted of a mix of aerobic, strength, and balance training. For the first six months, participants worked with a trainer twice a week. During the final three months, they had one supervised session and one unsupervised session.
"We found that exercise significantly improved physical performance, including balance and muscle strength at three and six months," May said.
But here's where it gets controversial: The study highlights the importance of balance, particularly since 74% of the patients had cancer that had spread to their bones. Low muscle mass and strength can worsen balance problems, especially when combined with nerve damage from cancer treatments. This makes fall prevention a critical concern, as bone metastasis increases the risk of fractures.
One participant, who initially struggled to get on and off a bus, regained her ability to do so after joining the exercise program. This seemingly small victory significantly improved her quality of life, allowing her to visit the city center and the library again.
The findings were presented at the Advanced Breast Cancer Eighth International Consensus Conference in Lisbon. The Advanced Breast Cancer Global Alliance plans to launch a Physical Activity Resource Hub in early 2026. This hub will provide videos, exercise guides, and resources tailored for patients with varying levels of breast cancer and fitness.
Eva Schumacher-Wulf, editor-in-chief of the German cancer magazine Mamma Mia!, emphasized the need for targeted exercise programs, acknowledging that not all exercise programs are suitable for individuals with advanced cancer.
And this is the part most people miss: These findings underscore the importance of integrating supervised exercise, especially with a resistance component, as a standard part of cancer care for patients with metastatic breast cancer.
