According to the American Cancer Society's Cancer Facts & Figures 2019 report, an estimated 268,600 new cases of breast cancer are expected to be diagnosed this year, and 42,260 people are anticipated to die of the disease in 2019. The ACS reports that "the overall 5- and 10-year relative survival rates for women with invasive breast cancer are 90 percent and 83 percent respectively."

In the simplest terms, these rates describe "the number of people that have lived once they've been diagnosed with the disease," says Dr. Dawn L. Hershman professor of medicine and epidemiology at Columbia University Medical Center/New York Presbyterian Hospital. This information may also sometimes be conveyed as mortality rates, which track "the number of people who die annually with the disease. Part of the reason we track (survival rates) is to see whether the incidence of cancer is increasing or if people are dying less once they develop the disease," Hershman says.'
