Almost Half of Cancer Deaths are Preventable

Data show that smoking, drinking alcohol and obesity are the biggest contributors to cancer worldwide.

Using estimates of cancer cases and deaths from more than 200 countries, researchers found that avoidable risk factors were responsible for nearly 4.5 million cancer deaths in 2019 (see ‘Global cancer deaths’).
