A recent Australian study reveals that one training session could slow tumor growth thanks to proteins released by muscles. A promising discovery for post-care breast care.
Breast cancer affects nearly 60,000 women in France each year. If medical advances have made it possible to considerably increase survival rates, recurrences remain frequent, with 15 to 20 % of patients who see the disease return within 10 years. In this context, activity physiquephysique For a few years has imposed itself as a real complementary “drug” capable of acting not only on the quality of life, but also directly on the biology of the disease. A new Australian study strengthens this conviction: according to researchers at Edith Cowan University, only one exercise session is enough to increase myokine levels, a protein that could reduce the growth of cancer cells up to 30 %.
Physical exercise, a natural trigger for anti -cancer substances
Directed by researcher Francesco Bettariga, this study followed survivors of breast cancer who participated in a single training session in résistancerésistance or offractional trainingfractional training high intensity (HIIT). The results are amazing: exercise stimulated the release of Myokines, produced by muscles during effort and known for their ability to curb tumor growth.
Francesco Bettriga, insists: ” The results of the study show that the two types of exercises really contribute to the production of these anticancer myokines in breast cancer survivors. These results constitute excellent motivations to integrate physical exercise into the basic care of cancer treatment. »
Other studies confirm the importance of sport in improving the survival rate in breast cancer. A meta-analysis published in Annals of Oncology had already shown that an increase of 10 weekly physical activity (about 2 and a half hours of fast walking) was associated with a 24 % reduction in breast cancer mortality.
The risk of breast cancer recurrence remains a reality for many women, even after treatments. The results of this Australian study suggest that a simple exercise session could become a new tool to help them regain power over their health. © Graphicroyalty, Adobe Stock
Reduce inflammation, another key to recurrence prevention
The benefits of the exercise do not stop at the production of myokines. Another study from Edith Cowan University also puts lightlight Another central mechanism: reducing chronic inflammation. In people treated for cancer, persistent inflammation promotes tumor progression, decreases theimmunityimmunityand increases the risks of recurrence.
« Breast cancer treatment, which may include chemotherapychemotherapythe radiotherapyradiotherapy or thehormone therapyhormone therapycould increase inflammation in the body. Chronic inflammation can increase the risk of breast cancer recurrence, as it can promote the progression and development of cancer cells », said M. Bettariga.
By reducing the massemasse Grasse and by increasing muscle mass, exercise regulates inflammatory markers.
“Our research has revealed that three inflammation markers were significantly reduced by a regular exercise, which is a very encouraging result “Added Mr. Bettariga.
Beyond figures and biological mechanisms, this study emphasizes the importance of making physical activity accessible, even in small doses. A session is enough to induce a beneficial response, which opens the way to short, suitable, and personalized programs, even in patients tired by treatments.
