Engaging in moderate- to high-intensity aerobic exercise two to three times a week, combined with resistance training, may help lower the risk of breast cancer recurrence, according to a new study. Researchers from Edith Cowan University (ECU), Australia, revealed that despite medical advancements, breast cancer recurrence remains a major concern, contributing significantly to mortality rates. In more aggressive cases, recurrence risk can be as high as 20 to 30 percent.
Exercise as a potential shield against recurrence The study, published in the JNCI: Journal of the National Cancer Institute, highlights that a combination of aerobic and resistance training may reduce pro-inflammatory biomarkers, which are often triggered by cancer treatments. Aerobic exercises—such as swimming, running, and stair climbing—paired with resistance training, including pushups and bench presses, were found to have a positive impact on inflammation levels. ECU doctoral researcher Francesco Bettariga explained, “Breast cancer treatments like chemotherapy, radiation, and endocrine therapy can increase inflammation in the body.
Chronic inflammation may fuel cancer cell progression and heighten the risk of recurrence.” The research discovered that three key inflammatory markers were significantly reduced through consistent exercise, a promising breakthrough in cancer recovery. How exercise helps in reducing inflammation Although the exact mechanisms are still being studied, researchers believe.
