This review article discusses basic radiation physics and effects of radiation on wounds. It examines various postulated hypothesis on the role of circulatory decrease and radiation-induced direct cellular damage. The new concept related to the radiation pathogenesis proposes that there is a cascade of cytokines initiated immediately after the radiation. Sustained activation of myofibroblasts in the wound accounts for its chronicity. Recent advances highlight that transforming growth factor beta1 is the master switch in pathogenesis of radiation fibrosis. This articles overviews its role and summarises the available evidences related to radiation damage. The goal of this article was to provide its modern understanding, as future research will concentrate on antagonising the effects of cytokines to promote wound healing.
