Abstract: The wavelet transform modulus maxima method was used to reveal changes in skin temperature dynamics of woman breasts with and without malignant tumor.The statistics of temperature temporal fluctuations about the cardiogenic and vasomotor perfusion oscillations do not change across time-scales for cancerous breasts as the signature of homogeneous monofractal fluctuations.This contrasts with the continuous change of temperature fluctuation statistics observed for healthy breasts as the hallmark of complex multifractal scaling.The study shows that multifractal analysis of dynamic IR imaging can be effectively used for preliminary screening in asymptomatic women to identify those with risk of breast cancer.+ , where h(x) is the Hölder exponent characterizing the singularity of Σ located at position t to which lt (a) points.The Legendre transform of the scaling function (q) in Eq. ( 2), is the singularity spectrum D(h) defined as the Hausdorf dimension of the set of points x where the Hölder exponent value is h:
