[1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
Non-fibrous particulate materials that cause cancer include powdered metallic cobalt and nickel, and crystalline silica (quartz, cristobalite, and tridymite). [32] Usually, physical carcinogens must get inside the body (such as through inhaling tiny pieces) and require years of exposure to develop cancer. [32] Common occupational carcinogens ...

[53] 1992 Fukuda et al. prove ingestion of H. pylori causes gastritis in rhesus monkeys. [4]
Increasing antibiotic resistance is the main cause of initial treatment failure. Factors linked to resistance include mutations, efflux pumps , and the formation of biofilms . [ 156 ] [ 157 ] One of the main antibiotics used in eradication therapies is clarithromycin , but clarithromycin-resistant strains have become well-established and the ...
