A young patient of Dr. Michael Lock received some terrible news.

Already on the liver transplant list for a non-cancerous ailment, the patient had been diagnosed with a malignant tumour in her liver. That made her ineligible for a transplant and she was classified as terminally ill.

But that didn't stop Dr. Lock, a radiation oncologist with the London Regional Cancer Program. He treated her cancer using focused radiation in a program that he had himself developed.
