Primary Outcome Measures
NameTimeMethod
The main deliverable is a set of PA/USCT breast images from healthy breasts, breasts containing malignant lesions, breasts containing benign lesions and all contralateral breasts. Furthermore, images acquired using conventional imaging modalities: x-ray and/or US and MRI will be collected in stage 2. For the patients who had to undergo a biopsy, we will also perform extensive pathology investigations as described in the study design.
Secondary Outcome Measures
NameTimeMethod
We ask the radiologists to evaluate the breast density based on the MMG investigation. With this knowledge we can investigate the imaging performance and sensitivity of the PAMMOTH device in breasts with different densities.<br><br>All subjects will be asked to fill out a questionnaire. The questionnaire (F1) can be will contain questions on:<br>• Comfort / burden of the measurement;<br>• Personal information such as age, height, weight, breast size and moment in menstrual cycle at the time of measurement (if applicable).<br>This questionnaire gives us the opportunity to answer the following set of questions:<br>• Does the breast size influence the imaging performance and sensitivity of the PAMMOTH device?<br>• Does the menstrual cycle influence the imaging performance and sensitivity of the PAMMOTH device?<br>Other interesting questions may be defined during the study
