At a Toronto cancer centre, researchers are enrolling thousands of patients in a trial that asks one of medicine's most quietly urgent questions: can a vial of blood reveal what imaging cannot? The SHERLOCK trial, testing liquid biopsies that detect microscopic tumour DNA after treatment, seeks to transform the long aftermath of cancer survival — where fear of recurrence often outlasts the disease itself. If the science holds at scale, it may offer patients something rarer than a cure: a trustworthy answer.

Patients could benefit from earlier intervention, reduced unnecessary chemotherapy/radiation side effects, and improved survival outcomes. However, costs of new blood tests and experimental treatments may increase out-of-pocket expenses until standardized and covered by insurance.
Regulatory bodies (FDA, Health Canada) will need to establish approval pathways for liquid biopsy tests. Insurance coverage decisions will be critical for adoption. Healthcare systems may need to budget for new diagnostic infrastructure and experimental immunotherapy treatments. Potential cost-benefit analyses required to justify reimbursement.
