About one third of all cancers can be prevented
European Code Against Cancer 1) Do not smoke; if you smoke, stop doing so. If you fail to stop, do not smoke in the
presence of non-smokers.
2) Avoid Obesity.
3) Undertake some brisk, physical activity every day.
4) Increase your daily intake and variety of vegetables and fruits: eat at least five servings daily. Limit your intake of foods containing fats from animal sources.
5) If you drink alcohol, whether beer, wine or spirits, moderate your consumption to two drinks per day if you are a man or one drink per day if you are a woman.
6) Care must be taken to avoid excessive sun exposure. It is specifically important to protect children and adolescents. For individuals who have a tendency to burn in the sun, active protective measures must be taken throughout life.
7) Apply strictly regulations aimed at preventing any exposure to known cancer-causing substances. Follow all health and safety instructions on substances which may cause cancer. Follow advice of national radiation protection offices.

European Code Against CancerThere are Public Health programmes which could prevent cancers developing or increase the probability that a cancer may be cured:
1)Women from 25 years of age should participate in cervical screening. This should be within programmes with quality control procedures in compliance with “European Guidelines for Quality Assurance in Cervical Screening”.
2)Women from 50 years of age should participate in breast screening. This should be within programmes with quality control procedures in compliance with “European Guidelines for Quality Assurance in Mammography Screening”.
3)Men and women from 50 years of age should participate in colorectal screening. This should be within programmes with built-in quality assurance procedures.
4)Participate in vaccination programmes against hepatitis B virus infection.

Cancer Stigma
• Lance Armstrong Foundation conducted a survey on cancer stigma in 2008– Japan, Mexico, Russia, Argentina, Brazil, China, France, India, Italy,
South Africa– About 500 people polled in each country
• Survey showed that – Stigma continues to persist across countries, cultures and
communities– Caused by misinformation, lack of awareness, deeply engrained
cultural myths and fear– Opportunities to capitalise on shifting perceptions– Mass media are key resources for facilitating more positive attitudes

Journalists have a role to play in raising awareness about
modifiable cancer risks and counteracting fatalistic cancer
