According to the results of a major new clinical trial, adding a screening ultrasound examination to routine mammography reveals more breast cancers than mammography alone. This study also showed that supplemental ultrasound may be beneficial in women at high risk of breast cancer who could not, or would not, otherwise undergo a magnetic resonance imaging scan. The trial, however, also found that adding an ultrasound exam increases the rate of false positive findings and unnecessary biopsies.

A team of researchers from Indiana University School of Medicine and the Purdue School of Science at Indiana University-Purdue University Indianapolis have come up with the first three dimensional image of a chemotherapy agent targeting and binding to DNA. The study used X-ray crystallography to create the molecular level image of bleomycin bound to DNA.
