Breast Cancer by the Numbers

Breast Cancer by the Numbers

U.S. Breast Cancer Statistics

  • Nearly 1 in 8 women (about 12 percent) will develop invasive breast cancer in her lifetime.

  • In 2013, over 230,000 new cases of invasive breast cancer are expected to be diagnosed in women in the U.S. More than 64,640 cases of non-invasive breast cancer were also expected to be diagnosed.

  • A man’s lifetime risk of breast cancer is about 1 in 1,000.

  • More than 2,240 new cases of invasive breast cancer are expected to be diagnosed in 2013.

  • From 1995 to 2005, breast cancer incidence rates in the U.S. decreased by about 2 percent per year. The decrease was seen in women aged 50 and older. One theory to explain the lowered rates was the reduced use of hormone replacement therapy by women.

  • Almost 40,000 women are expected to die in 2013 from breast cancer.

  • Death rates from breast cancer have been decreasing since 1990 – especially in women younger than 50. Decreases in death rates are connected with treatment advances, earlier detection, and increased awareness.

  • Breast cancer rates are higher than those for any other cancer besides lung cancer for women in the United States.

  • Breast cancer is the most commonly diagnosed cancer after skin cancer in women in the United States.

  • White women are more likely to develop breast cancer than black women. However, in women under 45, breast cancer is more common in black women than white women. Overall, black women are more likely to die from breast cancer.

  • In 2013, there are more than 2.8 million breast cancer survivors in the United States.

  • A woman’s risk of breast cancer doubles if she has a first-degree relative (mother, sister, daughter) who has been diagnosed with breast cancer.

  • About 5 percent to 10 percent of breast cancers are linked to gene mutations inherited from one’s mother or father. Women with these mutations have up to an 80 percent chance of developing breast cancer during their lifetime. An increased chance of ovarian cancer is also associated with genetic mutations.

  • About 85 percent of breast cancers occur in women who have no family history of breast cancer. These occur because of genetic mutations that happen as a result of aging or life in general, as opposed to a genetic mutation.

  • The most significant risk factors for breast cancer are gender (being a female) and age (growing older.)
