Who Is at Risk?
- Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. Excluding skin cancer, breast cancer is the most common form of cancer in women in the U.S.11
- According to the American Cancer Society, it is estimated that 207,090 new cases of carcinoma in situ (CIS) breast cancer will be diagnosed among women in the U.S. in 2010 (CIS is noninvasive and is the earliest form of breast cancer).1
- Of the 739,940 new cancer cases in women in 2010 (excluding skin cancer), breast cancer alone accounts for more than 1 in 4 cancers (or 28%).1,3
- Breast cancer is the second-leading cause of cancer death among U.S. women (behind lung cancer) but it is the leading cause of cancer death for U.S. women between the ages of 20 and 59.11,5
- An estimated 39,840 women are expected to succumb to the disease in 2010.2
- Breast cancer is not exclusively a disease of women. Although male breast cancer is rare, about 1,970 new cases of breast cancer (less than 1%) will be diagnosed in men in 2010, and the number of men expected to succumb to the disease in 2010 is 390.4
- Every 2-1/2 minutes, a woman in the U.S. learns she has the disease.9
- Every 13 minutes, a woman in the U.S. dies of breast cancer.10
- Gender and age are the most significant risk factors for developing breast cancer. Every woman is at risk for developing breast cancer, and the chances of being diagnosed with it rises sharply after the age of 40.6
- The average age at which a woman is diagnosed with the disease is 61.8
- From ages 3039, the chance of being diagnosed with breast cancer is 1 in 233; from ages 4049, the chance is 1 in 69; from 5059, the chance is 1 in 38; and from 6069, the chance is 1 in 27.1
- While breast cancer is rare among women under 40, it does account for about 5% of all breast cancer cases. However, the five-year relative survival rate is lower (83%) for women who are diagnosed with the disease before age 40 compared to women diagnosed at age 40 and older.3
- Between 70% and 80% of women who develop breast cancer do not have a family history of the disease.6
- The chance of a woman dying from breast cancer is about 1 in 35 (about 3%).1
- Early detection and screening is key to surviving breast cancer the five-year survival rate for breast cancer in a localized stage for all races is 98% (localized stage is malignant cancer that has not spread to the lymph nodes or other sites outside the breast).3
- The five-year survival rate for breast cancer in a regional state (spread to regional lymph nodes) after early-stage diagnosis and treatment is 84%.7
- Among racial and ethnic groups, breast cancer has a higher incidence rate in white women than in African American/Black, Hispanic/Latina, Asian/Pacific Islander, or American Indian/Alaska Native women.3
- African American women have a higher incidence of breast cancer than white women before the age of 45 and are more likely to succumb to breast cancer at every age.3
- According to the American Cancer Society, over 2.5 million women with a history of breast cancer are alive as of January 1, 2006. Most of these women were cancer free, while others still had evidence of cancer and were undergoing treatment.3

- The following calculations were used for this statistic and includes cases of carcinoma in situ: 365 days x 24 hours/day x 60 minutes/hour = 525,600 minutes/year
525,600 minutes/year / 207,090 new breast cancer cases = 2.54 (rounded to 2.5) minutes/cases
- The following calculations were used for this statistic: 365 days x 24 hours/day x 60 minutes/hour = 525,600 minutes/year
525,600 minutes/year / 39,840 deaths/year = 13.19 (rounded down to 13) minutes/deaths
