“Everything causes cancer” is a common refrain nowadays. It seems like there are new stories every month about a food or lifestyle choice that can increase your risk.
Things like deodorant, bras, and coffee have all been disproven as cancer-causing entities, but still people have their doubts, despite evidence to the contrary. California ruled in the spring of 2018 that coffee should be labeled as a possible cancer-causing agent, but research does not support the ruling and it’s expected to be appealed.

How do we separate truth from fiction? Maybe you’ve read several articles online supporting a certain cause of cancer, and seeing it so many times adds to its validity. Maybe people close to you believe certain ideas, and then it’s shared countless times over and somehow becomes fact instead of myth. Or perhaps there are experts in naturopathy or alternative medicine in your life that you respect a great deal that tell you certain things are cancer-causing. Maybe it’s better to be safe than sorry. Maybe “Big Pharma” is out to get us all.
It’s enough to drive you crazy, and it’s hard to know what to believe.
A recent study out of England gives us a sampling of how many people believe cancer risk factors that have been scientifically proven, and how many many people believe in fake cancer causes — and the effect this has on their lifestyles.
A survey published in the European Journal of Cancer shows that a significant amount of people know some valid cancer risks, but a startling number also believe in some “fake” cancer causes.
Researchers at University College London and the University of Leeds surveyed 1,330 people across England. About half the people surveyed correctly and confidently identified actual causes of cancer, while a little more than a third incorrectly (but confidently) cited scientifically unsupported causes of cancer.
According to Cancer Research UK, lifestyle changes could prevent roughly 4 in 10 cases of cancer. The three biggest risk factors under our control are: being overweight, sunburn (UV exposure), and smoking. Other proven causes are excessive alcohol consumption, contracting HPV, a sedentary lifestyle, and poor diet.
Most people surveyed (about 88%) knew that smoking increased cancer risk, and 80% knew second-hand smoke increased risk. Roughly 60% knew that sunburn increased risk.
However, a large percentage of people believed some things caused cancer that haven’t been proven at all.
43% think that stress causes cancer.
42% think that food additives cause cancer.
35% think that electromagnetic frequencies cause cancer.
34% think that eating GMO products causes cancer.
19% think that microwave ovens cause cancer.
15% think that drinking from plastic bottles cause cancer.
Strangely enough, just because people believe those things cause cancer doesn’t stop them from using them. On the flip side, it also didn’t increase use of them or increase risky behavior, meaning it didn’t cause them to give up on being healthy.
The believers in the proven causes still had an edge on the myth-believers, though. Those surveyed who were aware of the proven causes of cancer were more likely not to smoke, and also ate more fruits and vegetables than their myth-believing counterparts.
Our beliefs do impact our lifestyle choices, so it’s important to look at what’s been proven as opposed to what’s only conjecture or rumor. Of course, as long as you’re staying healthy, you do you. If you don’t want to use a microwave to reheat food or drink out of a plastic bottle, more power to you. Just be wary when someone or some site declares “THIS CAUSES CANCER” without any sort of scientific support (and maybe don’t pass judgement on your loved ones that do drink out of water bottles or use a microwave).
And as always, talk to your doctor if you’re unsure.
