A sobering number. About one in eight women will be diagnosed with breast cancer in her lifetime.

That's one reason doctors recommend women get a yearly mammogram beginning at age 45.

But for some women, mammograms won't detect their cancer, which is why, as Ali

Rogan reports, a new FDA requirement could identify more breast cancer cases and save lives.

Earlier this week, the FDA began requiring

that all mammogram reports disclose information

on a patient's breast density.

Higher breast density not only puts patients at higher risk of developing breast cancer, it can also make

cancers more difficult to detect, meaning patients may require additional screening.

Joanne Pushkin is the executive director of

dense breast info.org. She's also an advocate and breast cancer survivor herself.

Joanne, thank you so much a

a crucial thing to know about for anybody who has breasts.

Well, they're common and normal and most women have some level of

breast density in their breasts, but as density increases,

so does the likelihood that a cancer will be missed if it's present, and breast density in and of

itself is an independent risk factor for the development of breast

cancer. So for women with dense breast it can both hide cancer and increase

their risk and so they certainly need to know this information. Now that these

new FDA requirements have gone into effect,

what does that mean for a woman? Will it be that it's going to be in more plain

English than it has or just that there's a standardized language that's going to be
