It's Breast Cancer Awareness Month — 31 days of pink ribbon events. Here are some other numbers to know about breast cancer.

1 in 8 women, or 12 percent, will get breast cancer sometime in their lives. For many women, it won't occur until they're an advanced age.

266,120 new cases of breast cancer in U.S. women are predicted this year by the American Cancer Society.

40,920 women will die of breast cancer in 2018, the ACS predicts; it's the second-leading cause of cancer death among women, behind lung cancer. Still, only 1 in 38 American women will die of breast cancer — 2.6 percent.

3.1 million U.S. breast cancer survivors is the current estimate.

1-2 years is how often the U.S. Preventive Services task force recommends women ages 50-74 get a screening mammogram.

40 percent is the overall estimate of reduced mortality among women because of screening mammograms.

60-69 years old is the age group most likely to avoid death by getting a screening mammogram.

40- to 49-year-olds should weigh the risks and benefits of getting a mammogram, the task force said, because of a higher risk of false positives, unnecessary biopsies and treatment of cancers that, if left alone, wouldn't kill women in their lifetime. Get a mammogram if you have a parent, sibling or child with cancer; know you have an underlying genetic mutation, such as the BRCA1 or BRCA2 genes; or have a history of chest radiation at a young age.

$16.5 billion was the cost of treating breast cancer in the U.S. in 2016. It's estimated to hit $20.5 billion by 2020. 1 in 8 U.S. cancer patients file for bankruptcy.

$180 billion is the annual cost of health care expenses and lost productivity related to breast cancer.
