Measuring cancer risk and the impact of prevention efforts

Prevention is an effective long-term strategy to reduce the burden of cancer and a key element in cancer control. Many behavioural, environmental, and occupational risk factors are modifiable by adjusting health behaviours like quitting smoking and changing public, home, and work environments with by-laws limiting exposure to second-hand smoke, or through clinical interventions like the human papillomavirus vaccine to prevent cervical cancer. Here you will find indicators that focus on some of the most common modifiable risk factors.
