A new method was recently developed byDuane of Boston which obviates to a greatextent the difficulties created both by thesize and location of the tumor. It consists inthe use of buried radium emanation tubes. The Rationale of Radiumtherapy in Cancer 561 Each minute glass tube contains not morethan about 3 millicuries. A sufficient numberof the tubes is buried in the tumor to coverits whole mass and is left there permanently.The emanation decays after a time and thetubes become inert. While this method is simpler and fre-quently more efficient than the external ap- external application of radium in combina-tion with incomplete surgery and become themethod of choice in many conditions. Themethod of buried emanations should alwaysbe accompanied, however, by external appli-cation in the areas of the regional lymphglands and the areas directly adjoining thetumor.

Shows new boneformation. plication of radium, one must not lose sightof the fact that the action of the buriedemanation is not as strictly selective as theexternal application of well-filtered rays.The emanation in the minute tubes is filteredonly by the glass walls of the latter. There-fore the soft beta rays also act on the tumorand may produce small foci of necrosisaround the buried tubes. Care must be taken,therefore, not to place the tubes too near thesurface of the tumor nor too near largeblood vessels or nerves. Neither must theemanation tubes be placed too near eachother. But with correct technique thismethod will in the near future supersede the THE CORRECT FUNCTION OF RADIUM ANDTHE .i-RAYS IN CANCER THERAPY, There has developed in some quarters re-cently a tendency to apply to a cancer patient
