The data obtained indicate that AOA of a tumor and adjacent normal tissues is reasonably changed as the tumor grows. The character of these changes is analogous to the AOA changes, observed while inducing experimental tumors in animals, which evidence some common physico-chemical mechanisms of tumors occurrence and growth in animals and man. This concept may be supported by a resemblance of the response (by AOA changes) to the irradiation effect on tumor and tumor-bearer tissues, obtained both on experimental and clinical materials. The fact, that in each separate case a correlation between tumor AOA values and those of normal tissues is strictly individual (in the presence of a general tendency for the average tumor growth for each stage), seems to offer the opportunity to use the AOA test in prognosticating the radiotherapy effect for each particular case.
