We are currently updating our preventable cancers analysis. For all risk factors except smoking, and where risk factors are compared, the data is for 2015. For smoking alone, the data is for 2023. All other risk factors' data will be updated to 2023 later this year.
Nearly 1 in 2 people born in the UK in 1961 will be diagnosed with some form of cancer during their lifetime.

A person’s risk of developing cancer depends on many factors, including age, genetics, and exposure to risk factors.
Around 4 in 10 UK cancer cases every year could be prevented, that’s more than 135,000 every year (2015).
Nearly 112,000 England cases, around 13,000 Scotland cancer cases, around 7,200 Wales cancer cases, and around 3,500 Northern Ireland cancer cases every year could be prevented (2015).
Lung cancer, bowel cancer, melanoma skin cancer, and breast cancer together account for almost two-thirds of all preventable cancer cases in the UK (2015).
For 10 cancer types, including two of the five most common cancer types in the UK (lung cancer and melanoma skin cancer), more than 70% of UK cancer cases were attributable to known risk factors (2015).
Smoking is the largest cause of cancer in the UK (2015).
Overweight and obesity is the UK’s biggest cause of cancer after smoking (2015).
Overexposure to ultraviolet (UV) radiation, exposure to certain substances at work, exposure to certain infections, drinking alcohol, and eating too little fibre each cause 3-4% of cancer cases in the UK (2015).
Exposure to ionising radiation and eating processed meat each cause 1-2% of cancer cases in the UK (2015).
Exposure to outdoor air pollution and doing too little physical activity each cause 1% or less of cancer cases in the UK (2015).

Smoking is the largest cause of cancer in the UK (2015), accounting for 14% of all cancer cases (2023).
11.9% (more than 1 in 10) UK adults currently smoke cigarettes, that’s around 6 million people.
Cigarette smoking prevalence among adults in Great Britain has been decreasing for decades.
Cigarette smoking in adults in the UK is more common in more deprived groups.

Overweight and obesity is the UK’s biggest cause of cancer after smoking, causing more than 1 in 20 cancer cases in the UK (2015).
More than 6 in 10 UK adults (aged 16+) are overweight or obese (body mass index 25 or above).
Overweight and obesity prevalence among adults in England and Scotland has overall increased since the early 1990s.
Overweight and obesity in adults in the UK is more common in more deprived groups.
More than 6 in 10 UK adults (aged 16+) are overweight or obese (body mass index 25 or moreabove), that’s around 34.4 million people.
Overweight and obesity prevalence among adults in the UK generally increases until late middle-age and then decreases in older adults.
Overweight and obesity prevalence among adults in England and Scotland has overall increased since the early 1990s.
Overweight and obesity in the UK is more common in more deprived groups.
