Breast cancers found with annual mammograms over 10 years

Skip Navigation
In women who have a mammogram every year for 10 years, about 19 out of 1,000 women ages 40 to 49 will be diagnosed with breast cancer; about 30 out of 1,000 women ages 50 to 59 will be diagnosed with breast cancer; and about 44 out of 1,000 women ages 60 to 69 will be diagnosed with breast cancer.

Mammograms can find some breast cancers early, when the cancer may be more easily treated. Often a mammogram can find cancers that are too small for you or your doctor to feel.

The numbers in the graphic include women who are expected to be diagnosed with invasive breast cancer or an early form of noninvasive breast cancer called ductal carcinoma in situ.

The information shown here is based on the best available evidence.
