[Methodological aspects in studying the radiation pathomorphosis of human tumors]

The paper discusses methodological aspects of radial pathomorphism of human tumors. Its main feature is a type change of clinico-anatomical features of some nosological forms of malignant tumors under the influence of radiation therapy. Morphological manifestations of radial pathomorphism are variable, but its criteria require systematization. The development of radial changes occurs step-wisely and is characterized by structural-functional rearrangement of the tumor and circumflex normal tissues.
