The effect of therapy of malignancies is at present monitored by X-ray procedures on the basis of the dynamics of the size of lesion. Since such approach fails to provide data on the structure of lesion changes and response to treatment, it is suggested that structural changes in cells of exposed tissues can by monitored by using densitometric data obtained from mammograms and (computed) tomograms, to assess density changes in tumor and adjacent normal tissues. Recovery involves certain systemic changes which can be identified using certain peripheral blood indices; the latter are evaluated using non-statistical applications of the theory of pattern recognition and cluster analysis.
