Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [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.
Tumor-homing bacteria are facultative or obligate anaerobic bacteria (capable of producing ATP when oxygen is absent or is destroyed in normal oxygen levels) that are able to target cancerous cells in the body, suppress tumor growth and survive in the body for a long time even after the infection. When this type of bacteria is administered into ...
Killer T-cells surround cancer cell. Gut microbes may play a role in cancer development through a variety of mechanisms. Sulfate-reducing bacteria produce hydrogen sulfide, which results in genomic DNA damage. [28] Higher rates of colon cancer are associated with higher amounts of sulfate-reducing bacteria in the gut. [28]
Efforts to induce this phenomenon have used cancer vaccines (derived from cancer cells or selected cancer antigens), or direct treatment with immune-stimulating factors on skin cancers. [53] Some oncolytic viruses are very immunogenic and may by infection of the tumour, elicit an anti-tumor immune response, especially viruses delivering ...
Aflatoxin B 1, a toxin produced by the fungus Aspergillus flavus which is a common contaminant of stored grains and nuts is a known cause of hepatocellular cancer. The bacteria H. Pylori is known to cause stomach cancer and MALT lymphoma. [24] Hepatitis B and C are associated with the development of hepatocellular cancer.
Field cancerization or field effect (also termed field change, field change cancerization, field carcinogenesis, cancer field effect or premalignant field defect) is a biological process in which large areas of cells at a tissue surface or within an organ are affected by carcinogenic alterations. The process arises from exposure to an injurious ...
