A little late, but we were honored to attend the Cancer Research UK #CRUK #CancerGrandChallenges last week. We had a blast updating the group on the progress of Team OPTIMISTICC (OPportunity To Investigate the Microbiome’s Impact on Science and Treatment In Colorectal Cancer). We saw some really exciting science from the other grand challenge teams and look forward to seeing the new teams as we fight to cure and prevent cancer.
