摘要

In most low- and middle-resource countries (LMCs), breast cancer incidence rates are increasing more rapidly than in regions where incidence rates already are high. Despite the younger age structure of most developing countries, LMCs already account for 45% of the incident breast cancer cases and cause 54% of the annual breast cancer deaths around the globe. Even assuming (conservatively) that there will be no change in underlying age-specific rates, a nearly 50% increase is anticipated in breast cancer global incidence and mortality between the years 2002 and 2020 caused simply by the aging of current global populations. These rising cancer rates will be disproportionately greater among countries in the developing world, and the rates in LMCs are projected to reach a 55% increased incidence and a 58% increased mortality in <20 years.In reality, these projected statistics probably underestimate future cancer rates, because the few data available from LMCs reveal increasing age-specific breast cancer incidence and mortality rates, especially among recent birth cohorts. This is especially true for urban women in LMCs and is attributable in part to the adoption of Western lifestyles
