Besides the sub-cutaneous tissue will tolerate fromthree to five times as much radiationas the skin. The result of radium inmalignancy depends upon whether alethal dose is given. Formerly it wasconcluded, because our best radio-grams were taken with comparativelylow tubes, that this form of radiantenergy was the most suitable for deeptherapy. Almost every one overlookedthe loss of energy by absorption in thetissues and by divergence of the rays,and practically nothing was knownabout the lethal dose of different typesof malignant cells. Most radiologistscompared everything with the amount. Figure III.—Advanced carcinoma ofthe vlth marked axillary in-volvement. Tliirty-six radium needlesInBerted for six hours. Disease Inthe glands and the breast has en-tirely retrogressed and the patientis clinically cured. of radiant energy necessary to destroyrodent ulcer; and when the squamouscell epithelioma, axillary nodes and acancerous mass in the breast did notdisappear under x-ray, the radiationwas considered useless. The real factwas that a lethal dose had not beengiven. Radiation for the treatament of car-cinoma of the breast has been sochanged by imbedding radium thatwhere only superficial skin effects wereformerly produced, now cancerous tis-sue deeper than that which can be re-moved by the knife can be destroyedwithout opening the lymphatic chains.
