At 25, D’Arcy Bowker went from half‑marathon training to blackouts, soaring blood pressure, and a diagnosis of a rare tumour. When her cancer later spread, Dr. Wong from The Princess Margaret enrolled D’Arcy in a groundbreaking theranostics clinical trial. The treatment brought her disease under control, giving D’Arcy precious time with her growing family. Now a mother of three, D’Arcy shares how innovative cancer care helped save her life and inspired her to support others living with chronic illness.
