From The Conversation:
The fixation on potentially cancer-causing chemicals in the air, food and consumer products is diverting attention from the real risks, according to a review of global evidence by an Australian cancer researcher.
Writing in the medical journal The Lancet Oncology, Professor Bernard Stewart, from the University of New South Wales, said that lifestyle factors – driven by “personal choices” – were the most significant proven causes of cancer.
“Measures known to prevent cancer include smoking cessation, reducing alcohol intake, curbing obesity and avoiding deliberate sun exposure,” said Professor Stewart, who reviewed medical literature from around the world on known and suspected cancer hazards.
“Diverting attention from these messages threatens to undermine their efficacy to deliver proven benefits.”
