Study: Women with 'dense' breasts at no greater risk of dying from breast cancer

More women are getting the word they may have breasts too dense for mammograms to give a good picture. What's not so clear is what to make of that information.

Past research has shown an increased risk of cancer in women whose breasts are considered dense, or less fatty, but a new study in the Journal of the National Cancer Institute finds that may not be so.

Researchers tracked more than 9,000 breast cancer survivors. Those with very dense breasts were no more likely to die than similar patients whose breasts weren't as dense.

Tumors might be found later in dense breasts, but once they were diagnosed, they apparently weren't more aggressive or harder to treat.
