  • A person’s risk of developing cancer depends on many factors, including age, genetics, and exposure to risk factors (including some potentially avoidable lifestyle factors).
  • Cancer risk factors are overall similar worldwide. Smoking, insufficient physical activity, alcohol, diet, overweight and obesity, and infections account for a high proportion of cancers worldwide, as they do in the UK.
  • Prevalence of different risk factors varies by region and country, this is partly why overall cancer incidence rates, and the most common types of cancer, also vary by region and country.
  • Smoking is the single most preventable cause of death in the world, and around a third of tobacco-caused deaths are due to cancer (2015 projected). Most of the world’s smokers live in low- or middle-income countries.
  • Alcohol drinking causes an estimated 6% of deaths worldwide, around 1 in 8 of which are due to cancer (2012). Alcohol drinking prevalence is highest in Europe and America.
  • Unhealthy diets, e.g. high in fruit and vegetables and low in salt, are becoming more common in lower-resource countries.Overweight and obesity are leading causes of death worldwide.
  • Overweight and obesity prevalence is increasing particularly in low- and middle-income countries.
  • Infections cause 18% of the global cancer burden, with a much higher proportion in low-income countries.

The latest incidence and mortality statistics available for cancer worldwide are 2012 (estimated).

All cancers combined excludes non-melanoma skin cancer (NMSC)

The ICD codes Open a glossary item for all cancers combined are ICD-10 C00-C97 (excluding C44).

Some common cancers are defined using slightly different ICD codes in this section than used for the UK data.

An understanding of worldwide data quality is relevant to interpreting these stats.
