The cancer diagnostic chain
remains a fragile process
susceptible to human error

Imagine you feel a lump in your breast. Your doctor sends you to get a mammogram, which is read by radiologist who trained for many years to recognize faint patterns of suspicious masses. The region in question does not clearly fit the
common pattern for a benign mass, so you
get a needle biopsy to extract a piece of tissue
from the suspected area for further testing.
The sample gets sent to a lab, where a technician slices
the tissue and fixes it on a glass slide. Like the radiologist,
the pathologist is another human trained to interpret visual
patterns. She scrutinizes the slide, inspecting the tissue at
high magnification for regions of cells that look abnormal.
