Fig. 5. Distributions of cell nuclear area values and internuclear distances in the breast tumor specimens (Figs. 3 and 4), where bin interval = 8 and n = 30 for each distribution.

(A) Histogram of the cell nuclear cross-sectional areas imaged by UV-PAM (Figs. 3C and 4C). The green dashed line is a Gaussian fit for lymphocytes, with a mean of 32.8 μm² and an SD of 7 μm². The red dashed line is a Gaussian fit for cancer cells, with a mean of 67.6 μm² and an SD of 11 μm². (B) Histogram of the cell nuclear cross-sectional areas imaged by histology (Figs. 3D and 4D). The green dashed line is a Gaussian fit for lymphocytes, with a mean of 30.1 μm² and an SD of 6.7 μm². The red dashed line is a Gaussian fit for cancer cells, with a mean of 66 μm² and an SD of 9.2 μm². (C) Histogram of the internuclear distances imaged by UV-PAM (Figs. 3C and 4C). The green dashed line is a Gaussian fit for lymphocytes, with a mean of 13.1 μm and an SD of 3.8 μm. The red dashed line is a Gaussian fit for cancer cells, with a mean of 15.4 μm and an SD of 2.4 μm. (D) Histogram of the internuclear distances imaged by histology (Figs. 3D and 4D). The green dashed line is a Gaussian fit for lymphocytes, with a mean of 13.2 μm and an SD of 4.1 μm. The red dashed line is a Gaussian fit for cancer cells, with a mean of 17.2 μm and an SD of 2.9 μm.
