he cervix and uterus. For the earlier lung cancer study, cells were brushed from the cheek. For the colon, cells came from the rectum, and for the pancreas, cells came from the duodenum. Cells from these neighboring organs showed changes at the nanoscale when cancer was present.

PWS can detect cell features as small as 20 nanometers, uncovering differences in cells that appear normal using standard microscopy techniques. PWS measures the disorder strength of the nanoscale organization of the cell, which is a strong marker for the presence of cancer in the organ or in a nearby organ.

The PWS-based test makes use of the "field effect," a biological phenomenon in which cells located some distance from the malignant or pre-malignant tumor undergo molecular and other changes.
