Description of intervention(s) / exposure
This study will assess the diagnostic accuracy and safety of the ORM-P3-D System. The ORM-P3-D System is a handheld optical imaging system for intra-operative use during Breast Conserving Surgery (BCS) used by the surgeon and viewed on a screen during surgery.
The investigator (breast surgeon) will undergo a 1 hour face-to-face training session with OncoRes Medical Pty Ltd on the use of the ORM-P3-D system, at least a month before commencement of intervention. The training involves handling of the device with a phantom model, interpretation of images and review of precautions, warning and contraindications.
Participants will undergo standard of care breast conserving surgery (1-2 hour surgery) for breast cancer. During the surgery the investigational medical device will be used to guide the excision of tissue by measuring optical and mechanical properties of the tissue. Adherence to the study protocol during intervention will be supervised by a member of the site research team and recorded as an electronic case report form in the trial database.
Participants will take part in 3-4 study visits over 5 months. At the end of the trial participants will continue to receive standard of care treatment for their condition at the Institution.

Comparator / control treatment
There are no control participants in this study, however diagnostic accuracy of the device will be compared against:
1) Standard of care initiated shavings during index procedure. Surgeons will use clinical judgment to determine which cavity margins will be shaved and inform the study personnel for recording in the study database, prior to device use.
2) Histopathology assessment. Study images acquired will be compared with routine histology of shavings to assess the primary and secondary outcome measures.

Summary
Brief summary
The research project is testing a new imaging device for use during breast conserving surgery, involving the use of a medical device called ORM-P3-D System. The purpose of this study is to find out the diagnostic accuracy and safety of the ORM-P3 System during breast conserving surgery for patients with breast cancer. Who is it for? You may be eligible for this study if you are a woman aged 18 years or older, you have been diagnosed with invasive or in situ breast cancer and you are eligible to undergo breast conserving surgery as part of your cancer treatment. Study details All participants who choose to enrol in this study will be asked to attend 3-4 study visits scheduled over a 5 month period. The first visit will be a screening visit to determine whether you are eligible to enrol in the study. Those participants who are eligible to enrol will continue with their standard cancer care and will be scheduled for a breast conserving surgery. The surgery will be undertaken per standard protocols, with the addition of the ORM-P3-D medical device. During the surgery, the surgeon will use the device to scan the breast tissue. The device will provide images on the tissue's optical and mechanical properties on a micro-scale. After the surgery, participants will be asked to attend a final study visit where a surgical review and adverse event assessment will be undertaken. It is hoped this research will determine whether use of the ORM-P3-D System is effective at identification of residual cancerous tissue within the breast-conserving surgery (BCS) cavity.
