Just One Salmonella Infection Leads to Colon Cancer Risk, Study Finds
A new study has linked Salmonella exposure to a heightened risk of colon cancer. Led by Jun Sun, Ph.D. from the University of Illinois Chicago, researchers observed human colon cancer tissue samples and animal models, finding that exposure to Salmonella may be linked with instances of colon cancer that develop earlier and have larger tumor growth.
The present study builds on a prior, Netherlands-based retrospective study of colon cancer patients that found Salmonella antibodies to be present in tissue samples from people who had poor oncological outcomes. Using the same Salmonella strains isolated from the tissue samples, Dr. Sun and her based team observed mice with colon cancer after exposure to the pathogen.
