COVER Illustration of gut microbial species assembling into the shape of a cancer awareness ribbon. Cancer patients with an abundance of different gut bacteria have better survival outcomes after checkpoint inhibitor immunotherapy, whereas patients with depleted gut flora respond poorly to this treatment. Thus, modulating the microbiome may provide hope for improved cancer patient responses. See pages 32, 91, 97, and 104.
