Doctors at Princess Margaret Cancer Centre and The Hospital for Sick Children are helping detect cancer in some patients before a tumour develops or shows up on a medical scan.

They analyzed results from a sophisticated blood test using technology called 'cell-free DNA' to see when cancer could be developing. The promising findings have been published in Cancer Discovery.

Care for Luana and Juliet under"The Toronto Protocol" has already been a game changer. Doctors say they can detect cancer even earlier using the results from routine blood tests. He said patients compare living with Li-Fraumeni syndrome to a time bomb, wondering when the next shoe will drop."We're able to tell you your cell-free DNA signal seems high, looks like you're going to get a cancer quite soon, let's investigate a little bit more in-depth," he said.

"We now have a test that should be applied to any form of hereditary cancer, and the implications of that are huge because we know a significant portion of the population develops their concerns because they are at risk." The research was also co-authored by Dr. Trevor Pugh at PMCC and primarily funded by the Terry Fox Research Institute.
