There is a clear divide between higher and lower socioeconomic groups when it comes to knowledge and awareness of cancer risks, and as a result, the practice of behaviours to limit such risks.
This was the result of a global survey commissioned by the Union for International Cancer Control (UICC) to form an up-to-date picture of the public’s experiences, views and behaviours around cancer.
Conducted by market research company Ipsos, the survey includes more than 15,000 adults across 20 countries in the first multi-country public survey on cancer perceptions in a decade.
The survey’s results are detailed in the report International Public Opinion Survey on Cancer 2020: What people feel, think and believe about cancer today, which was released on World Cancer Day 2020.
Said UICC chief executive officer Dr Cary Adams: “It is unacceptable that millions of people have a greater chance of developing cancer in their lifetime, because they are simply not aware of the cancer risks to avoid and the healthy behaviours to adopt – information that many of us take for granted.
“And this is true around the world.”
Awareness of cancer risks
The survey’s results show that there is generally a high level of cancer awareness among the surveyed population globally.
Tobacco use (63%), exposure to harmful UV (ultraviolet) rays (54%) and exposure to tobacco smoke from others (50%) appear to be the most recognised factors that can increase a person’s risk of cancer.
Meanwhile, a lack of exercise (28%), exposure to certain viruses or bacteria (28%), and being overweight (29%), appear to be the least recognised cancer risk factors.
However, individuals from a lower-income household bracket in the countries surveyed are less likely to recognise cancer risk factors than those from higher-income households.
In all areas except tobacco use, this trend can also be seen when comparing people surveyed who have not completed a university education to those with university educations.
With less awareness of the main risk factors associated with cancer, these individuals appear less likely to proactively take the steps needed to reduce their cancer risk than those from a high-income household or with a university education.
Of the individuals surveyed, 32% were “somewhat concerned” about cancer, while 26% were “very concerned”.
Meanwhile, 17% were “not very concerned” and 14% were “not concerned at all”.
A total of 2% were already living with cancer, while 10% preferred not to express their concern about cancer.
In addition, an overwhelming 84% of individuals surveyed felt that governments should be taking action in relation to cancer.
Nearly a third of individuals surveyed believed that it is most important for governments to improve the affordability of cancer services – a measure notably emphasised by people surveyed in lower middle-income countries.
UICC president Princess Dina Mired of Jordan said: “To tackle the global cancer burden now and for the future, governments and decision-makers across the international cancer community must come together to ensure that everyone is afforded every opportunity to take control over their cancer risk, no matter their education or income level.”
To help raise greater awareness around cancer and to support health-promoting behaviours so that no one gets left behind, UICC is calling for all governments to:
- Prioritise cancer awareness raising and prevention through progressive health policies and education to support healthy decisions and health-promoting behaviour, with a focus on engaging lower socioeconomic populations.
- Ensure the public is provided with up-to-date information on cancer risks and cancer prevention, and importantly, that the information is presented and delivered in a way that is accessible by individuals from lower socioeconomic backgrounds,
- Implement policies to help reduce the consumption of known cancer-causing products (e.g. tobacco, sugary food and beverages) to encourage health-promoting behaviours, particularly among lower socioeconomic groups.
- Invest proactively in national cancer control planning and the establishment of population-based registries to ensure the most effective resource allocation that benefits all groups.
- Continue to raise awareness with each new generation to help ensure that up-to-date information on cancer risks and cancer prevention is not taken for granted.
UICC also recommends that everyone as individuals:
- Use World Cancer Day as an opportunity to improve your understanding of cancer risk factors and share your knowledge with others.
- Make a personal commitment to reduce your cancer risks, like quitting smoking, eating healthily, exercising regularly and using sunscreen.
- Take advantage of what your health system can provide, including getting a check-up, getting screened and getting vaccinated.
