Breast Cancer Statistics
In the United States, breast cancer has the highest mortality rate of any cancer in women between the ages of 20 and 59. The American Cancer Society predicted that in 2020, about 276,480 new cases of invasive breast cancer will be diagnosed in women and 2,620 for men; with about 42,170 women and 520 men expected to die from breast cancer. As of early 2016, the National Cancer Institute (NCI) estimated that there are more than 3.5 million breast cancer survivors in the U.S. (women are living with a prior diagnosis of breast cancer).
A U.S. woman’s lifetime risk of breast cancer increased steadily and dramatically from the 1930s, when the first reliable cancer incidence data was established, through the end of the twentieth century. Between 1973 and 1998, breast cancer incidence rates in the United States increased by more than 40%.
In recent years, incidence rates have increased slightly, by .3% per year. Today a US woman’s lifetime risk of breast cancer is about 13%. This means there is a 1 in 8 chance she will develop breast cancer. Female breast cancer represents 15.2% of all new cancer cases in the U.S. Breast cancer is the second leading cause of cancer death in women (only lung cancer kills more women each year). The chance that a woman will die from breast cancer is 1 in 38, or about 2.6%.
As cancer incidence data have become more nuanced over the past decade, it is clear that the incidence of breast cancer varies considerably by a number of factors, including age and ethnicity.
Historically in the US, breast cancer incidence has been higher in white women than in African American women. However, in 2016, incidence in African American women caught up with that of white women. Further, among women younger than 45, breast cancer incidence is higher among African American women than white women. Younger women in general, and younger African American women in particular, are more likely to present with the triple-negative subtype of the disease, a diagnosis that is both more aggressive and associated with a higher mortality.,
Across racial and ethnic groups in the U.S., African American women have the highest breast cancer mortality rate of any racial/ethnic group (28.9 deaths per 100,000 women, age-adjusted and normalized to the 2000 standardized U.S. population). Asian and Pacific Islander women have the lowest mortality rates (11.3), with White (20.6), Hispanic (14.3) and American Indian/Native American (14.5) women having intermediate mortality rates based on cancer registry data.
Despite the universal drop in mortality rates across the past two decades and the similarity in incidence rates, over the same time period the disparities between mortality rates for white and black women have grown significantly. The mortality rate for black women diagnosed with breast cancer is 42% higher than the comparable rate for white women.
