The regulation of cancerous tumor development is converged upon by multiple pathways and factors besides environmental factors, gastrointestinal (gi) tract cancer can be caused by chronic inflammation, which is generally induced by bacteria, viruses, and parasites. 4 author mah lee, et al worked on “epstein-barr virus associated gastric cancer and its clinical characteristics” epstein-barr virus is associated with a variety of lymphoproliferative disorders. Common oncogenic viruses in western developed countries, human papillomavirus (hpv), hepatitis b virus (hbv) and hepatitis c virus (hcv) are the most frequently encountered oncogenic dna viruses human papillomavirus worldwide, hpv causes the second largest fraction of infection-associated cancers or 52% of the global cancer burden. Oncogenic viruses can contribute to different steps of the carcinogenic process, and the association of a virus with a given cancer can be anywhere from 15% to 100% in addition to elucidating the etiology of several human cancers, the study of oncogenic viruses has been invaluable to the discovery and analysis of key cellular pathways that.
Infection of the epstein-barr virus causes about 15% of stomach cancers, most nasopharyngeal cancers (cancer of the nasopharynx, the region behind the nose and above the back of the throat), and certain types of lymphomas known as burkitt or.

Besides environmental factors, gastrointestinal (gi) tract cancer can be caused by chronic inflammation, which is generally induced by bacteria, viruses, and parasites the role of these inducers in cancer development, cell differentiation and transformation, cell cycle deregulation, and in the expression of tumor-associated genes cannot be ignored.
Viruses possess significant oncogenic potential to interfere with normal cell cycle control and genome stability, stimulating the growth of deregulated cells besides environmental factors, gastrointestinal (gi) tract cancer can be caused by chronic inflammation, which is generally induced by bacteria, viruses, and parasites the role of.

To date, there are seven oncogenic viruses [human papillomavirus (hpv), epstein–barr virus (ebv), hepatitis virus b and c (hbv and hcv), human t-cell lymphoma virus 1 (htlv-1), merkel cell polyomavirus (mcpyv), and kaposi’s sarcoma virus (ksvh or hhv8)], one oncogenic bacterium (helicobacter pylori), and three oncogenic parasites (schistosoma haematobium, opithorchis viverrini, and clonorchis sinensis), identified as cancer-related pathogens. Viruses in particular have been found to play a major role in the tumorigenic process involving several organs: the human papillomavirus (cervical cancer), the herpes viruses (kaposi sarcoma), human and simian polyomaviruses (mesothelioma, brain tumors), the epstein–barr virus (b-cell lymphomas, nasopharyngeal cancer), the human t-cell leukemia virus-1 (t-cell leukemias), and the hepatitis b and c viruses (hepatocellular carcinoma.
