Fig. 3.

10x magnification FOVs of common out-of-domain tumor tissues.

In each FOV, each ROI with a red circle indicates a region that the ROI classified as cancer. We use this indicator to differentiate out-of-domain ROIs from the metastatic breast cancer ROIs in the primary test set.

3A. High-grade carcinoma FOV with model cancer classifications.

3B. Papillary thyroid cancer FOV with model cancer classifications.

3C. Papillary urothelial carcinoma FOV with model cancer classifications.

3D. Endometrial carcinoma FOV with model cancer classifications.

3E. Embryonal carcinoma FOV with model cancer classifications.

3F. Serous borderline tumor FOV with model cancer classifications.
