Researchers at UHN's Princess Margaret Cancer Centre have launched a landmark study, known as SHERLOCK, that uses a blood test to detect small traces of cancer that may remain in a patient's body after treatment. The traces are known as molecular residual disease (MRD), small cancer signals in the blood often not detected with standard testing methods, such as CT or MRI scans, or even more invasive tests like tissue biopsies.

More than four decades since the beginning of the AIDS epidemic, a generation of patients once told they had no future are living into their senior years.

"There was no cure, no help. It was devastating." HIV is transmitted sexually and through blood.
