One of the biggest risk factors for liver, colon or stomach cancer is chronic inflammation of those organs, often caused by viral or bacterial infections. A new study from MIT offers the most comprehensive look yet at how such infections provoke tissues into becoming cancerous.

The study, which is in the online edition ofProceedings of the National Academy of Sciences the week of June 11, tracked a variety of genetic and chemical changes in the livers and colons of mice infected with Helicobacter hepaticus, a bacterium similar to Helicobacter pylori, which causes stomach ulcers and cancer in humans.

The findings could help researchers develop ways to predict the health consequences of chronic inflammation, and design drugs to halt such inflammation.

“If you understand the mechanism, then you can design interventions,” says Peter Dedon, an MIT professor of biological engineering. “For example, what if we develop ways to block or interrupt the toxic effects of the chronic inflammation?” …

Infection Causes 1 in 6 Cancers Worldwide: Study

From the 9 May 2012 Medical News Today article

WEDNESDAY, May 9 (HealthDay News) — One in six cancers worldwide is caused by preventable or treatable infections, a new study finds.

Infections cause about 2 million cancer cases a year, and 80 percent of those cases occur in less developed areas of the world, according to the study, which was published online May 8 in The Lancet Oncology. Of the 7.5 million cancer deaths worldwide in 2008, about 1.5 million were due to potentially preventable or treatable infections.

“Infections with certain viruses, bacteria and parasites are one of the biggest and most preventable causes of cancer worldwide,” lead authors Catherine de Martel and Martyn Plummer, from the International Agency for Research on Cancer in Lyon, France, said in a journal news release. “Application of existing public-health methods for infection prevention — such as vaccination, safer injection practice or antimicrobial treatments — could have a substantial effect on future burden of cancer worldwide.”…
