I'm not sure if this is against the rules, but the CBC (Canadian Broadcasting company) on their "Marketplace" program had a very interesting and informative program. Wendy Mesley, a TV reporter, was diagnosed with BC. After all her treatments she investigated why there is such a proliferation of cancer, and why there is no emphasis on prevention, other than "Make Healthy Choices".
The CBC website also has quite a bit of info, and you can also download the program. ***Disclaimer --I am in no way affiliated with the CBC!!
