Rates of change in lumpectomy and mastectomy sites.

THb = total hemoglobin; s’> = reduced scattering coefficient.Rate of change per minute (fitted values from the model) for each tissue parameter of the benign (n = 13) and malignant (n = 7) sites measured in mastectomy specimens and benign (n = 59) sites measured in the lumpectomy specimens. Reported values indicate the average ± standard deviation. P-values indicate the statistical differences in the rate of change between the benign and malignant mastectomy sites.
