Rise in Belief in Cancer Myths

Rise in Belief in Cancer Myths

cancer myths belief

Research has found that the number of people who believe in unproven causes of cancer has increased.

A survey of over 1,000 people has revealed that a significant proportion of people believe myths around cancer, such as that drinking from plastic bottles causes cancer, or that eating genetically modified food increases your risk of getting cancer.

Risk factors

The survey, carried out by researchers from University College London and the University of Leeds and funded by Cancer Research, interviewed 1,330 people in England. They were asked whether they were aware of certain known risk factors for cancer. They were also asked whether they believed a series of cancer myths, for which there is no scientific evidence.

The people surveyed were asked how much they agreed that the items on the list increased a person’s chances of developing cancer, using a five-point scale ranging from strongly disagree to strongly agree.

Cancer myths

The myths that were most commonly believed were stress (which 43% of people said they thought causes cancer), food additives (42%) and electromagnetic frequencies (35%).

Other mythical causes of cancer that were thought to be true were eating genetically modified food (34%), microwave ovens (19%) and drinking from plastic bottles (15%).

A quarter of people said they thought that using a mobile phone is a risk factor for cancer, and three in 10 said they believed that living near power lines could increase the risk.

Scientifically proven

Of the scientifically proven causes of cancer, 88% correctly picked smoking, 80% picked passive smoking and 60% picked sunburn.

Only 30% of people knew that carrying the human papilloma virus (HPV) can cause cancer, or that not eating enough fruit and vegetables can cause cancer. There was also low awareness of other known cancer risk factors such as drinking alcohol and being obese.

Fake cancer news

One theory behind the increase in belief in cancer myths is the increase in ‘fake news’ on the internet and social media. 

Dr Samuel Smith from the University of Leeds said: “Compared to past research it appears the number of people believing in unproven causes of cancer has increased since the start of the century which could be a result of changes to how we access news and information through the internet and social media.

“It’s vital to improve public education about the causes of cancer if we want to help people make informed decisions about their lives and ensure they aren’t worrying unnecessarily.”
