Substantial contribution of extrinsic risk factors to cancer development

Editor’s summary []:

 “Recent analyses have suggested that for some cancers, the intrinsic behaviour of tissue stem cells may be responsible for malignant transformation and cancer progression, raising the question of the influence that extrinsic factors may have on tumorigenesis. Yusuf Hannun and colleagues provide evidence that stem cell dynamic-related intrinsic risk factors contribute only marginally to cancer development and are not a major factor in the observed cancer risk. This new analysis indicates that tumour progress is influenced by extrinsic factors, and highlights the importance of taking them into account in cancer prevention.”

Does Cell-Phone Radiation Cause Cancer?

As the debate over cell-phone radiation heats up, consumers deserve answers to whether there’s a cancer connection

“In May 2015, a group of 190 independent scientists from 39 countries, who in total have written more than 2,000 papers on the topic, called on the United Nations, the World Health Organization, and national governments to develop stricter controls on cell-phone radiation. They point to growing research—as well as the classification of cell-phone radiation as a possible carcinogen in 2011 by the International Agency for Research on Cancer, part of the WHO—suggesting that the low levels of radiation from cell phones could have potentially cancer-causing effects.”

Genetically Engineered Food: An Overview

“New technologies — like genetic engineering — create uncertainties and risk that should be carefully evaluated rather than being rapidly pushed onto the market.”

“For centuries, farmers were able to use generations’ worth of knowledge to breed seeds and livestock for the most desirable traits. However, technological innovation has gradually made this method of breeding nearly obsolete. Today, most soybeans, corn and cotton have been genetically engineered — altered with inserted genetic material — to exhibit traits that repel pests or withstand the application of herbicides.”

GMO pigs' cautionary tale of genetically modified food research

For decades, genetically modified crops such as corn and canola have been a common -- if still controversial -- part of Canada's food system. 

Now, new advances in genetic modification are poised to make it possible to put genetically modified animals on our dinner plates as well.”

Vitamins and Supplements: Magic Pills

 “As many as three out of four Canadians use natural health products.

Big Pharma and Organized Crime — They are More Similar Than You May Think

 “It is scary how many similarities there are between this [pharmaceutical] industry and the mob. The mob makes obscene amounts of money, as does this industry. The side effects of organized crime are killings and deaths, and the side effects are the same in this industry. The mob bribes politicians and others, and so does the drug industry …” ~ former vice-president of Pfizer pharmaceuticals

Tough Medicine—A disturbing report from the front lines of the war on cancer.

 “The Death of Cancer is an angry book, in which one of the critical figures in twentieth-century oncology unloads a lifetime of frustration with the obduracy and closed-mindedness of his profession. [Vincent] DeVita concludes, ‘There are incredibly promising therapies out there. If used to their fullest potential for all patients, I believe we could cure an additional 100,000 patients a year.’ He is not the first to point out the shortcomings of clinical practice, of course. What sets The Death of Cancer apart is what he proposes to do about it.”
