Breast Cancer Statistics
Do you know the real statistics about breast cancer in the United States? Here is a quote from the Fact Sheet developed by the National Breast Cancer Coalition (www.stopbreastcancer.org);
- The National Cancer Institute estimates that a woman in the United States has a 1 in 8 chance of developing invasive breast cancer during her lifetime. This risk was about 1 in 11 in 1975.
- More women in the United States are living with breast cancer than any other cancer (excluding skin cancer). Approximately 3 million women in the U.S. are living with breast cancer: about 2.3 million have been diagnosed with the disease and an estimated 1 million do not yet know they have the disease.
- Breast cancer is the most commonly diagnosed cancer among women in the United States (excluding skin cancer). In 2008, it is estimated that 250,230 new cases of breast cancer will be diagnosed among women in the US: 182,460 invasive breast cancers and 67,770 cases of in situ breast cancer (of which 85% will be ductal carcinoma in situ (DCIS)). In 2008, approximately 1,990 new cases of invasive breast cancer will be diagnosed among U.S. men.
- The incidence of breast cancer declined between 2001 and 2004. It is believed that a drop in the use of hormone replacement therapy is responsible for the decline, but there are other possible reasons as well, and these are being studied.
- Breast cancer is the second leading cause of cancer death for women in the U.S, after lung cancer. Approximately 40,460 women and 450 men in the U.S. will die from the disease in 2008. Breast cancer is the leading cause of cancer death for U.S. women between the ages of 20 and 59, and the leading cause of cancer death for women worldwide.
- Approximately 11% of women diagnosed with invasive breast cancer die from the disease within five years; at ten years, 20% will have died. The most recent available statistics show that 40% of all women diagnosed with invasive breast cancer died from the disease within 20 years.
