Without the harmful side effects that come with chemotherapy, immunotherapy is the preferred method to treat many cancers today, yet positive response rates to this type of therapy fall somewhere south of 60%. Why so low? Because gut bacteria play a heavy role in metabolism and immunity, they can ultimately determine the fate of a medication’s effectiveness. And in those who suffer from dysbiosis (imbalanced gut bacteria), the likelihood of a positive response to immunotherapy is lower than those with a balanced, diverse microbiome. In fact, both human and animal studies show that taking antibiotics within a short timeframe before starting immunotherapy results in lower response rates. Researchers have also compared the microbiomes of those who respond well to immunotherapy and…
