Exercise Boosts Cancer-Fighting Proteins Slowing Breast Cancer Growth

Recent studies highlight the significant role of exercise, particularly resistance training (RT) and high-intensity interval training (HIIT), in supporting breast cancer survivors by increasing anti-cancer myokines—proteins that help suppress cancer cell growth. Research involving breast cancer survivors showed that a single session of these exercises elevated levels of these beneficial proteins, with HIIT demonstrating stronger immediate effects, potentially lowering the risk of recurrence. Exercise also improves mental health, physical strength, tolerance to treatment side effects, and overall quality of life during cancer therapy, as reported by patients and oncologists alike. Additionally, physical activity during chemotherapy is linked to better treatment outcomes, including improved physical function, reduced fatigue and depression, and enhanced survival rates, though many patients still struggle to meet recommended activity levels. These findings underscore the importance of tailored exercise regimens as a complementary approach to cancer treatment and survivorship care. Furthermore, maintaining a healthy body weight remains critical, as excess weight may increase breast cancer risk, especially in postmenopausal women with cardiovascular conditions.
