Description of intervention(s) / exposure
This multidisciplinary one year study will consist of a cohort of 60 patients who have ductal carcinoma in situ (DCIS) or invasive breast cancer, as confirmed by biopsy. Thirty minutes prior to theatre, the patient is injected with 150MBq of f18flurodeoxyglucose (FDG) through a cannula placed in the contra-lateral arm to the breast of interest. Once the specimen has been surgically removed and orientated, the Surgeon will use the beta probe to record counts within the surgical cavity, recording the same orientated surfaces as for the excised tissue. The excised tissue will be orientated and the counts recorded for each of the six surfaces (superior, inferior, medial, lateral, superficial, deep) using the beta probe. The gamma probe will then be used over the excised tissue to verify the sample contains FDG positive tissue. In this initial study there would be no action taken on these findings.

Outcomes
Primary outcome [1] 257817 0
Accuracy of the PET probe. Counts per second in areas where the probe has detected FDG will be recorded on the data collection sheet. This will be compared to the histology results, and in particular the clearance of the surgical margins and where there was not clearance, distance between the DCIS of invasive tissue and the margin/s.

Review all data after one year worth of recruitment
Secondary outcome [1] 263235 0
Confirm probe protocol. A good sensitivity and specificity based on the primary outcome confirms the protocol (injection dose and timing) is correct.

Summary
Brief summary
This study is examining if the use of a PET probe during surgery for DCIS or breast cancer can accurately determine if all of the cancer cells have been removed. Currently 20% of patients require a second operation due to potential remaining cancer cells in the breast. Identification of these cells at the time of the first operation may reduce the number of women requiring second
operations. This will have an impact on the patient (time & distress) and the health care system.
