This book will be welcomed by every one interested in the subject of gastric cancer, for it contains the results of Konjetzny's life work. The author is a recognized authority, and in this volume he presents new material and fits it together with older observations to present a complete picture, not only of the development of gastric carcinoma but of present day therapeusis of the most common visceral malignant change. In view of the impossibility of preventing cancer, early diagnosis and radical surgical measures are needed.
There is a certain inherited tendency or organic disposition to carcinoma, but cancer as such is not inherited. Cancer is apparently neither contagious nor infectious. The Cohnheim theory of development from immature embryonal cells has been discarded. Trauma is not significant except as it relates to the results of destruction of the mucosa, as in acid or alkali poisoning, with subsequent regeneration and heteroplasia.
