Per American Cancer Society, breast cancer is the most common cancer in women in the United States, except for skin cancers. It is about 30% (or 1 in 3) of all new female cancers each year. Overall, the average risk of a woman in the United States developing breast cancer sometime in her life is about 13%. This means there is a 1 in 8 chance she will develop breast cancer.
Breast cancer death rates have been decreasing steadily since 1989, for an overall decline of 43% through 2020. The decrease in death rates is believed to be the result of finding breast cancer earlier through screening and increased awareness, as well as better treatments.
New American College of Radiology® (ACR®) breast cancer screening guidelines now call for all women, particularly Black and Ashkenazi Jewish women, to have risk assessment by age 25 to determine if screening earlier than age 40 is needed. The ACR continues to recommend annual screening starting at age 40 for women of average risk, but earlier and more intensive screening for high-risk patients.
