Аннотация:In the paper, the results of experimental investigations on the differences of wool structure of
healthy mice and mice with malignant tumor (s) are represented. It is shown that destruction
of wool structure happens during pathology development. Quantity of cells of external wool
layer and their thickness decrease when the tumor capsule enlarges. Difference is seen
even when the tumor is small. The obtained results can be used to improve optical
techniques of biomedical diagnostics of cancer diseases.
