That the F.nucleatum bacterium is associated with colon cancer has been known for some time, e.g.: https://pubmed.ncbi.nlm.nih.gov/27876571/

It is also associated with "poor rates of both overall survival and progression-free survival" in cervical cancer: https://pubmed.ncbi.nlm.nih.gov/33197886/

And it is "associated with shorter survival" when found in esophageal cancer: https://pubmed.ncbi.nlm.nih.gov/27769987/

It is also linked to gastric cancer: https://www.nature.com/articles/s41598-017-18596-0

All in all, it's obviously a pretty nasty little customer. It might be worth screening for it, and attempting to eliminate it if possible.
