A thin rubber tube placed over thisone and sealed at one end serves the double purposeof a filter and of keeping the radium tube clean.

Fig. 245.—Diagram to illus-trate method of introduc-ing radium tubes into lowerbowel. In Cancer of the Prostate Gland This may be treated by four methods : (1) By the rectum. (2) By tubes introduced into the bladder. The tube is enclosed in acatheter. (3) By a number of tubes introduced into the substance of the gland.The perineal route may be employed. (4) Post-operative treatment. Tubes can readily be introduced intothe bladder after operation. When treating by method No. 1 radium should be filtered through2 mm. of platinum. Comparatively long exposures may be given, up totwelve to fifteen hours, using 100 mgi-ms. of radium. R.IDIUM IN CANCER 377 No. 2.—This does not allow of very thick filters, therefore the ejr^osuresmust be reduced proportionately. By method No. 3, provided the tubes can be quite surrounded by thegrowth, comparatively long exposures may be given. After complete removal of the prostate gland radium tubes should beleft in the tissues at the base of the bladder
