Researchers out of Lawson Health Research Institute in London, Ont. have developed a new tool that they believe can greatly improve surgery outcomes and reduce time in the operating room for breast cancer patients.
Surgeries for breast cancer usually involve either complete breast removal or removal of a tumour, which is called breast conserving surgery.
Dr. Jeffrey Carson’s laboratory is behind the new tool — a hand-held photoacoustic imaging probe.
“In real time, the surgeon can go in there, detect that tumour, cut it away, and then go back with the probe and verify that they’ve got all of the tumour,” he explained to 980 CFPL.
The hand-held photoacoustic imaging probe provides major improvements in breast conserving surgery, which currently involves surgeons waiting for data to determine whether or not all cancerous cells were removed.
“The wait was anywhere from 20 minutes to an hour,” said Dr. Muriel Brackstone, associate scientist at Lawson and head of the Breast Care Clinic at St. Joseph’s Hospital London.
Under the status quo, roughly one in five surgeries fails to catch all of the cancerous cells. The team, however, believes the new tool — which can catch up to 75 per cent of missed tumour cells in real time — can reduce that rate to one in 20.
