Breast cancer deaths over 10 years with or without annual mammograms

In women who have a mammogram every year for 10 years versus those who do not, about 3 out of 1,000 women ages 40 to 49 who have mammograms will die from breast cancer versus between 3 and 4 who do not have mammograms; about 6 out of 1,000 women ages 50 to 59 who have mammograms will die from breast cancer versus about 7 who do not have mammograms; and about 9 out of 1,000 women ages 60 to 69 who have mammograms will die from breast cancer versus 13 who do not have mammograms.

Studies done in women show that a small number of those who have mammograms may be less likely to die from breast cancer.

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.
