Breast Cancer Risk by Age

The risk of getting breast cancer increases with age. The table below shows the percentage of women (how many out of 100) who will get breast cancer over different time periods. The time periods are based on the woman’s current age.

For example, go to current age 60. The table shows 3.46% of women who are now 60 years old will get breast cancer sometime during the next 10 years. That is, 3 or 4 out of every 100 women who are 60 years old today will get breast cancer by the age of 70.
