Breast cancers diagnosed during the first three years after childbirth, particularly within the first year, may be biologically more aggressive than similar cancers in women who have never given birth, according to a study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center.
For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early. To make earlier diagnosis easier, a Massachusetts Institute of Technology team has developed portable detectors based on ultrasound, which could be used much more frequently. The team reports that they have improved the resolution of the images produced by their system, making it easier to spot potential tumors, as well as cysts and microcalcifications.
