The mechanism of the action of the rayson malignant tumors, the sequence of eventsas well as the fact that results obtainedthrough this action resemble the phenomenawhich occur spontaneously in the organism,can be demonstrated most clearly in thestudy of the influence which radium exertson carcinoma and sarcoma of the skeleton.
