Breast cancer care starts with
• A policy of breast care • Finding (small) cancers
• Treating the malignant cancers • Embrace the women to completely recover from cancer

Role of the medical physicist
• Understand • Simulate, design, predict, study, … grasp it
• Measure
• Establish a method, verify, robustness test, … get it
• Improve
• from understanding & measuring…

The medical physicist in breast imaging, 2017
Helps decide between the different options Creates evidence for the choices Teaches and explains Initiates proper breast care and QA in order to • to reduce breast cancer mortality • to avoid over diagnosis • to ensure true breast care in the whole wide world

Medical physicists to spread the messages
• that breast care is important • that imaging is useful • that radiation risks can be under control • that women deserve good care We have the ethical obligation to communicate all this also to the public.
