Organized national mammographic screening has been adopted as the gold standard for breast cancer early detection in western countries; however it may not be the most cost-effective approach to early detection in low and middle income countries (LMC) as it is very demanding in terms of human and financial resources. Moreover, its benefit to harm ratio has been questioned lately, particularly in women <50 years, the age group which produces the majority of breast cancer cases in LMC.
