Bacteria Promote Cancer by Enhancing Stem Cell Replication and Turnover

Bacterial infection has been linked to cancer risk in some cases, and here researchers propose that this is because the bacterial species can cause some stem cell populations to replicate more frequently. Greater cell activity in this fashion over time raises the risk of a cancerous mutation occurring. The authors of the study examine only the one case in which a bacteria-cancer association is well studied, but we might speculate on similar situations elsewhere in the body.
