At least one third of cancers are preventable giving us every reason to champion healthy choices and prevention strategies for all, so that we have the best chance to prevent and reduce our cancer risks.
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 preventable1 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)2. Quitting at any age can make huge a difference, increasing your life expectancy and improving quality of life3.
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 ten cancers, which include bowel, breast, uterine, ovarian, pancreatic, oesophagus, kidney, liver, advanced prostate and gallbladder cancers6,7.
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 cancer8. 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: Smoking is linked to 71%4 of lung cancer deaths, and accounts for at least 22% of all cancer deaths5.
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.
