"Cancer is a leading cause of death worldwide: it accounted for 7.4 million deaths (around 13% of all deaths) in 2004."
"More than 30% of cancer could be prevented by modifying or avoiding key risk factors, according to a 2005 study by international cancer collaborators1. Risk factors include:
- tobacco use
- being overweight or obese
- low fruit and vegetable intake
- physical inactivity
- alcohol use
- sexually transmitted HPV-infection
- urban air pollution
- indoor smoke from household use of solid fuels.
Prevention strategies:
- increase avoidance of the risk factors listed above
- vaccinate against human papilloma virus (HPV) and hepatitis B virus (HBV)
- control occupational hazards
- reduce exposure to sunlight"
