The classification of cases for radium treatment is similar to that givenunder X-ray therapeutics. RADIUM IN CANCER OF THE TONGUE AND MOUTH be This condition is frequently sent for radium treatment. Tubes mayburied in the growth, and benefit is occasionally obtained, though in. Fig. 241.—Radium tube arranged for the treatment of the floor of the mouth.

Cancer of the floor of themouth is a condition which does not respond favourably in a large numberof cases treated. When possible, tubes should be buried in the this is not done, a useful form of applicator may be used (see Fig. 241).A window can be cut in the lead tube surrounding the radium tube, the rayspassing through the window directly on to the growth, while the surround-ing tissues are protected to some extent by the thick lead.
