Thanks to earlier detection –through screening and increased awareness— and better treatments, a woman's risk of dying of breast dropped 38 percent between the late 1980s and 2014, translating into 297,300 fewer breast cancer deaths during that time.
However, breast cancer is still the second leading cause of cancer death in women. Only lung cancer kills more women each year. And there remains a large racial gap in mortality, with African-American women having 42 percent higher death rates compared to whites. The chance that a woman will die from breast cancer is about 1 in 37 (about 2.7 percent).
According to the American Cancer Society (ACS), in 2017:
- About 252,710 new cases of invasive breast cancer will be diagnosed in women.
- About 63,410 new cases of carcinoma in situ (CIS) will be diagnosed (CIS is non-invasive and is the earliest form of breast cancer).
- About 40,610 women will die from breast cancer.
- While black and white women get breast cancer at roughly the same rate, black women are more likely to die from it.
At this time, there are more than 3.1 million people with a history of breast cancer in the United States. (This includes women still being treated and those who have completed treatment.)
- Limited but accumulating research indicates that smoking may slightly increase breast cancer risk, particularly long-term, heavy smoking and among women who start smoking before their first pregnancy.
- Obesity increases the risk of postmenopausal breast cancer. Risk is about 1.5 times higher in overweight women and about 2 times higher in obese women than in lean women.
- Growing evidence suggests that women who get regular physical activity have a 10%-25% lower risk of breast cancer compared to women who are inactive, with stronger evidence for postmenopausal than premenopausal women.
- Numerous studies have confirmed that alcohol consumption increases the risk of breast cancer in women by about 7%-10% for each one drink of alcohol consumed per day on average. Women who have 2-3 alcoholic drinks per day have a 20 percent higher risk of breast cancer compared to non-drinkers.
