Comparison between the normal cervical tissue and tissue lesion for different stages. From top to bottom are the pathological images for the normal cervical tissue (first row) and tissue lesion (second row), the photo image (third row) and corresponding DMAP images (fourth row) of representative experiments respectively. Margins of the normal tissue (green) and cervical lesion (red) are indicated in the photo and DAMP images. The scale bar for the histological images represents 0.1 $mm$, and that for the photo and DMAP images is 1 $mm$.
