Does fasting help make chemotherapy more effective in breast cancer patients? Researchers led by Leiden University Medical Centre (LUMC) and Breast Cancer Research Group (BOOG) are a step closer to answering that question after completing the first randomized study. They describe their auspicious results in the scientific journal Nature Communications .
Breast cancer is the most common cancer in women worldwide, with over 2 million new cases diagnosed per year, representing about 25 percent of all cancers in women. Like most other cancers, breast cancer depends on nutrients and growth factors to continue to grow and to resist and escape current standards of care. Conversely, short-term fasting has been shown to protect tumor-bearing mice against the toxic effects of chemotherapy, while enhancing therapeutic efficacy.
