breast cancer awareness

Mammography can prevent deaths from breast cancer, but it's not a perfect test.

It misses some cancers, especially in women with dense breast tissue, and flags abnormalities for follow-up tests that turn out to be benign, among other issues. So there's a lot of interest in additional tests that might make screening more accurate in women who have dense breasts.
