Based on tissues from 20 female patients (mean age: 53 years; rang: 36-72 years), we examine the performance of a room-temperature-operated terahertz (THz) fiber-scanning near-field microscopy to diagnose slices of breast tissues. The specimens were frozen sliced and then measured in a thawed state without dehydration. We performed the imaging at 320GHz. Our study indicates that images acquired in the THz transmission-illumination mode can all clearly distinguish breast tumor tissues from normal tissues without H&E staining. Due to its capability to perform quantitative analysis and to allow follow-up staining and traditional pathohistological analysis, our study indicates great potential of the THz fiber-scanning near-field microscopy for future automation, which is critical for fast and complete pre-screening on breast tumor pathological examinations and for assisting quick definition of the tumor margins during the surgical procedure such as breast-conserving surgery.
