Breast Cancer Statistics

Here are some breast cancer statistics (various sources):

  • Breast cancer is the most common type of cancer among women in the United States (after skin cancer), accounting for more than 1 in 4 cancers.
  • There is a new diagnosis every 3 minutes and a life lost every 14.
  • Breast cancer is the 2nd leading cause of cancer death in women, after lung cancer.
  • 1 out of 8 American women who live to be 85 years of age will develop breast cancer, a risk that was 1 out of 14 in 1960.
  • 2.4 million women living in the U.S. have been diagnosed with and treated for breast cancer.
  • About 80% of women diagnosed with breast cancer have no family history of breast cancer.
  • The American Cancer Society estimates that 211,000 new cases of breast cancer will be diagnosed this year and 43,300 patients will die from the disease. Breast cancer is considered an epidemic among women.
  • About 1.2 million cases of breast cancer will be diagnosed this year worldwide, according to the World Health Organization.
  • About 75% of breast cancers are found in women over age 50.
  • The chance of having breast cancer for a woman in her 50’s is about 1 in 50.  The chance of having breast cancer for a woman in her 90’s is about 1 in 9.
  • Breast cancer is uncommon in women younger than 35.  Most cases develop in women older than 50, and the risk increases as women pass 60, 70, and 80.
  • It has been estimated that 5–10% of breast cancer cases result from inherited mutations or alterations in BRCA1 and BRCA2.
  • Other risk factors include inherited mutations in the BRCA1 and BRCA2 genes, a personal or family history of breast cancer, high breast tissue density, high-dose radiation to the chest wall, long menstrual history, never having given birth or giving birth for the first time after age 30, and biopsy-confirmed atypical hyperplasia.
