Prognosis Poor for Breast Cancer

May 5, 2018
Is Prognosis Poor for Breast Cancer Diagnosed After Negative Screening Mammography?

Bottom Line: A study of mammography data for more than 300,000 women suggests cases of breast cancer diagnosed after a negative screening mammogram were more likely to be associated with poor prognosis than those cancers diagnosed after a positive screening mammogram.

Why The Research Is Interesting: The rate of breast cancer after negative mammography results is small but the likelihood these cases can be associated with poor prognosis highlights the need for early detection.
