Risk-attributable cancer burden varies by world region and sociodemographic index (SDI), with smoking, unsafe sex, and alcohol consumption being the top three risk factors in low SDI regions and smoking in high SDI regions , followed by alcohol consumption and weight gain

Between 2010 and 2019, cancer deaths due to risk factors increased by 20.

The study analysed the impact of 34 known risk factors identified by the World Cancer Research Fund on 23 cancers
