Cancer Prevention and Risk Reduction
At least one third of cancers are preventable, giving us every reason to champion healthy life choices and prevention strategies to reduce the risk of developing cancer.
Choosing Your Health
Not every type of cancer is preventable but we do know we can prevent many cancers through lifestyle choices alone. According to the World Health Organization, at least one third of common cancers are preventable through a healthy diet, maintaining a healthy weight and being physically active.
Tobacco use is the single largest preventable cause of cancer and stopping smoking is one of the best things we can do to reduce our risk of cancer. Use of tobacco has been found to cause around 15 different types of cancer including oral cancers, lung, liver, stomach, bowel and ovarian cancers, as well as some types of leukaemia (cancers of the blood). Quitting at any age can make huge a difference, increasing your life expectancy and improving quality of life1.
Alcohol is strongly linked with an increased risk of several cancers. By reducing and limiting how much you drink, you can reduce your risk of cancers of the mouth, pharynx, larynx, oesophagus, bowel and breast, and may also reduce the risk of liver and bowel cancers.
Maintaining a healthy weight and making physical activity part of your everyday life can help reduce your risk of several cancers, which include bladder, breast,
No matter where you live or your skin tone, moderate your exposure to ultraviolet radiation from the sun and avoid tanning beds and solariums to help reduce your risk of skin cancer. Staying under the shade, covering up your skin and avoiding prolonged periods of exposure to the sun are some ways to help protect yourself.
Fast fact: Tobacco causes 8 million deaths every year and accounts for at least 25% of all cancer deaths.
Some people risk being exposed to a cancer-causing substance because of the work that they do. For example, workers in the chemical dye industry have been found to have a higher incidence than normal of bladder cancer. Asbestos is a well-known workplace cause of cancer – particularly a cancer called mesothelioma, which most commonly affects the covering of the lungs. In this case, asbestos isn’t just present in workplaces but can also be found in older homes and buildings.
Chronic infections (commonly caused by viruses) are estimated to cause approximately 16% of all cancers globally. Some of the most common forms of cancers such as liver, cervical and stomach cancers are associated with infections with the hepatitis B virus (HBV), the human papillomavirus (HPV), and the bacterium Helicobacter pylori virus (H, pylori), respectively. Today, there are safe and effective vaccines against HBV and HPV, which can help to protect against the infection-related cancers of liver and cervical cancers.
What can we do?
- As individuals we can take responsibility for our health, including getting vaccinated and reminding others to get vaccinated, maintaining a healthy and active lifestyle, avoiding alcohol, tobacco and excessive/prolonged sun exposure
- Governments and policy leaders can implement vaccination programmes to prevent infections that cause cervical and liver cancer. They can also regulate solariums and tanning salons, and ban the mining and export of asbestos
- Schools can provide information on cancer risk factors and be champions of healthy behaviours among children, staff, parents, families and the wider community, in particular, they can cultivate an environment that supports good nutrition and physical activity.
- Employers can implement policies in the workplace to prevent occupational exposure to cancer-causing agents, such as asbestos and other workplace carcinogens, as well as create smoke-free spaces and promote physical activity and healthy nutrition among its employees.
- Cities and communities can take the lead in creating a quality urban environment that promotes and protects the health and wellbeing of its citizens.
