Abstract
Purpose
Exclusive breastfeeding and longer breastfeeding reduce women’s breast cancer risk but Mexico has one of the lowest breastfeeding rates worldwide. We estimated the lifetime economic and disease burden of breast cancer in Mexico if 95% of parous women breastfeed each child exclusively for 6 months and continue breastfeeding for over a year.
Methods
We used a static microsimulation model with a cost-of-illness approach to simulate a cohort of Mexican women. We estimated breast cancer incidence, premature mortality, disability-adjusted life years (DALYs), medical costs, and income losses due to breast cancer and extrapolated the results to 1.116 million Mexican women of age 15 in 2012. Costs were expressed in 2015 US dollars and discounted at a 3% annual rate.
Results
We estimated that 2,186 premature deaths (95% CI 2,123–2,248), 9,936 breast cancer cases (95% CI 9,651–10,220), 45,109 DALYs (95% CI 43,000–47,217), and $245 million USD (95% CI 234–256) in medical costs and income losses owing to breast cancer could be saved over a cohort’s lifetime. Medical costs account for 80% of the economic burden; income losses and opportunity costs for caregivers account for 15 and 5%, respectively.
Conclusions
In Mexico, the burden of breast cancer due to suboptimal breastfeeding in women is high in terms of morbidity, premature mortality, and the economic costs for the health sector and society.
