Rutgers University Feb 5 2026 When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi – microorganisms that, if actually present in tumor tissues, could influence how they grow, evade immunity or respond to treatment. But do microorganisms truly reside in tumors, or do the samples become contaminated before sequencing occurs? Independent analyses of the same genomic data have reached wildly different conclusions. Now, researchers at
