If the projected trends continue, obesity as a cause of cancer in women will overtake smoking by 2043, the report says.
The figures for men are different as men are more likely to smoke and to get tobacco-related cancers. The gap between obesity and smoking as causes of cancer is expected to close much later than in woman.
While more males than females are overweight, obesity has a greater effect on women as some of the most common obesity-related cancers predominantly affect them, such as breast and womb cancers.
