Figure 2 shows the cancer margins observable with the polarized image versus the doctor's unaided eye. The margins of the cancer observed in the polarized image were 11 mm in diameter. The clinical margins observable by eye were only 6 mm in diamter. Although the polarized camera predicted a larger margin, the docotres surgically excised only a little beyond the 6 mm visible lesion as is normal practice. The histology came back with margins positive for cancer and the doctors had to reschedule surgery for another larger excision.
