A Global Burden of Disease analysis using data from more than 200 countries between 1990 and 2023 found that 28% of breast cancer healthy years lost are linked to six lifestyle and metabolic risk factors, and forecasts a rise in new cases from 2.3 million in 2023 to over 3.5 million by 2050.

In 2023, 28% of the global breast cancer burden, equivalent to 6.8 million healthy years lost, was linked to six potentially modifiable risk factors.
High red meat consumption had the largest single impact, linked to about 11% of healthy years lost to breast cancer.
Tobacco including secondhand smoke accounted for 8% of healthy years lost, high blood sugar 6%, high body mass index 4%, and both high alcohol use and low physical activity 2% each.
New breast cancer cases in women are projected to rise from 2.3 million in 2023 to more than 3.5 million by 2050.
In 2023 women aged 55 and older had three times the incidence per 100,000 of women aged 20 to 54, while incidence in the 20 to 54 age group has risen 29% since 1990.
Researchers warn the burden is shifting toward low and lower middle income countries where later diagnosis and limited access to quality care drive higher death rates.
