I was teaching Problem Based Learning to highschoolers last week, and decided to break from my two years of using AIDS as a topic and have them research cancer instead. As I was trying to recall the origins of oncogene names via Google, for my own edification, I came across the Cancer Bacteria Homepage, which insists that cancer is caused by bacterial infection, specifically by certain mycoplasms, and that cancer patients should give up their present therapies and go on an antibiotic regimen. This is one of those instances where the freedom of webspeech goes from humorous and quirky to indifferent and dangerous. The fact that the reams of evidence demonstrating how totally ineffective antibiotics are at fighting cancer can be so easily ignored just to have a provocative website at the expense of others' health seems more than a bit criminal to me.
