Breast Cancer Statistics
The good news: Mortality declined by 2% per year from 1990 to 2001, with the greatest declines in women younger than 50 years. Estimated deaths in 2007 = 40,910.
The bad news: An estimated 180,510 new cases will be diagnosed in 2007. The incidence has continued to gradually increase since 1990.
Recent decline in ER + breast cancer incidence may be secondary to 40% decline in use of hormone replacement therapy between 2000- 2003.
