Breast cancer epidemiology

The breast is the leading cancer site in women throughout the world. That said, breast cancer incidence varies widely, ranging from 27/100,000 (Central-East Asia and Africa) to 85-94/100,000 (Australia, North America and Western Europe). Its frequency in France is among the highest in Europe. While...

Summary:The breast is the leading cancer site in women throughout the world. That said, breast cancer incidence varies widely, ranging from 27/100,000 (Central-East Asia and Africa) to 85-94/100,000 (Australia, North America and Western Europe). Its frequency in France is among the highest in Europe. While in most countries, its incidence has been increasing for more than 40 years, in a few other countries (USA, Canada, Australia, France…), it has been decreasing since 2000-2005. Possibly due to a substantial reduction of hormone-based treatments at menopause, the decrease may be transient. It is also the leading cause of female cancer deaths in almost all countries, with the exception of the most economically developed, in which it is currently second to lung cancer. That much said, for thirty years in highly industrialized countries such as France, breast cancer mortality has been declining. Taken together, early diagnosis and improved treatment explain this success. In France, 5-year survival and 10-year survival approximate 88 % and 78 % respectively; these rates are among the most elevated in Western Europe. Excess mortality due to breast cancer is consequently low (
