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.
"I was relieved, and it was amazing to know this is what science can do," study participant Juliet Locke told CTV News Toronto in an interview. "Something as little as a tiny non-invasive poke can give you so much information."
Locke was 14 years old when she was diagnosed with leukemia. She and her mother, Luana, live with Li-Fraumeni syndrome (LFS), a rare inherited condition caused by a gene mutation (P53), which carries almost a 100 per cent lifetime risk of getting cancer.
As a result, doctors monitor them closely under what is known as "The Toronto Protocol." It's a surveillance system with regular MRIs, ultrasounds and blood tests to detect cancer as early as possible.
In Luana's family, her brother, nephew, mother and sister died from cancer.
