New research highlights progress in residual breast cancer
Image-guided biopsy of the tumor bed or residual abnormalities found on imaging after neoadjuvant chemotherapy is gaining popularity as a predictive tool for assessing residual cancer. The technique can help to identify exceptional treatment responders for de-escalation of local therapy, an international study has found.

Women express caution about trusting breast AI
A research group from the University of Groningen in the Netherlands surveyed more than 900 Dutch women in April 2020 to gauge their attitudes on using artificial intelligence (AI) for interpretation of screening mammograms. Over 75% of women didn't approve of standalone use of AI without a radiologist.
