Fig. 3From: Intratumoral heterogeneity of second-harmonic generation scattering from tumor collagen and its effects on metastatic risk predictionF/B in tumor-stroma interface versus tumor bulk. Collagen fiber internal structure, as represented by F/B, is significantly different between tumor bulk and the tumor-stroma interface in IDC ER+ LNN excised primary tumors.
