https://www.sciencedaily.com/releases/2022/09/220921141505.htm > Smoking is the main cause of preventable cancer and death in the UK, accounting for around 15% of all cancer cases in England in 2015. Cancer incidence also varies by socio-economic position across the UK, with the overall cancer incidence rate 17% higher in the lowest-income quintile of the population compared with the highest in England. > In the new study, the researchers focused on the 15 cancer types with strong evidence for an association with smoking -- which contribute over 8 in 10 deprivation-associated cancer cases in England. Smoking-attributable cancer cases in 2013-17 were calculated by combining cancer incidence with smoking prevalence (in 2003-07, allowing for the lag between smoking and cancer diagnosis) and relative risk of being diagnosed with cancer among smokers vs non-smokers. These smoking-attributable cases were then shown as a proportion of the deprivation-associated cancer cases total.
