In the cancer world, biopsies have long been considered a necessary evil. The cell and tissue samples collected through the procedure provide critical information about potentially cancerous tumours. But extracting those samples from areas of concern can be uncomfortable, and almost always involves a trip to the hospital.

In late-stage cases, when the disease has spread to the bones, biopsies can be incredibly painful, says Dr. Stuart Edmonds, executive vice president of mission, research and advocacy at the Canadian Cancer Society. Although these procedures can take a heavy toll on patients, he adds,“they help doctors understand cancers better, so they’re an important tool in oncology.”
