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 appearing in the online edition of Proceedings 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.

At the Frequency Research Foundation we have always found viruses associated with cancer and recent research on biofilms shows that they are always associated with cancer as well. NIH did DNA sequencing studies on over 600 biofilm species associated with gum disease. Over the last two years we have developed frequency sets for over 400 biofilm species and these frequencies are updated daily and available to Frequency Foundation Subscribers (see Paypal button on right).
