Breast Cancer: Most common cancer in developed and developing world 1.38 million cases in 2008 –Most frequent cancer in women (23% of all cancers) Incidence –19.3/100,000 women in East Africa –89.7/100,000 women in Western Europe GLOBOCON

5
Breast Cancer Mortality 6-19 per 100,000 due to more favorable survival in (high-incidence) developed regions Most frequent cause of cancer death in women in both developing (269,000 deaths) and developed regions (189,000 deaths).

Breast Cancer Rates are Rising… ‘Westernization' of lifestyles Urbanization Dietary habits and physical inactivity Changes in reproductive factors such as lower rates of childbearing Exposure to exogenous estrogen

Trends in Mortality

Berry D.A., et al. N Engl J Med. 353:1784-92, 2005 Decrease in breast cancer mortality

Breast cancer rates increasing- approaches require: Guidelines that are evidence-based, economically feasible, and culturally appropriate Early detection - metastatic disease is not treated successfully in ANY country Improved cancer registries and data collection Clinical trials in developing countries
