If you are interested in hearing about how a direct link between the formation of breast cancer among other diseases, and oral pathology has been proven, please listen to this interview (see link below or google blogtalkradio + undergroundwellness + fred hughes). Hearing this interview is what first lead me to discover I had cavitations in my jawbone as a result of improper wisdom tooth removal. Since then I have been able to verify it by by having a thermal imaging scan and a Cavitat scan done.

I understand some people were having trouble connecting to this link for some reason. If you just google "blog talk radio" and then do a search on their site for "Fred Hughes" the interview will come up that way as well.
