What are the key statistics about breast cancer?
Breast cancer is the most common cancer among American women, except for skin cancers. About 1 in 8 (12%) women in the US will develop invasive breast cancer during their lifetime.
The American Cancer Society's estimates for breast cancer in the United States for 2016 are:
- About 246,660 new cases of invasive breast cancer will be diagnosed in women.
- About 61,000 new cases of carcinoma in situ (CIS) will be diagnosed (CIS is non-invasive and is the earliest form of breast cancer).
- About 40,450 women will die from breast cancer
In recent years, incidence rates have been stable in white women, but have increased slightly in African American women.
Breast cancer is the second leading cause of cancer death in women, exceeded only by lung cancer. The chance that breast cancer will be responsible for a woman's death is about 1 in 36 (about 3%). Death rates from breast cancer have been declining since about 1989, with larger decreases in women younger than 50. These decreases are believed to be the result of earlier detection through screening and increased awareness, as well as improved treatment.
At this time there are more than 2.8 million breast cancer survivors in the United States. (This includes women still being treated and those who have completed treatment.) Survival rates are discussed in the section “Breast cancer survival rates by stage.”
