Inaddition to thorough radiation of theprmiary lesion, attention must be paid tothe neighboring lymph-nodes. If these arenot already palpably involved, they shouldbe thoroughly rayed with the .v-ray. Ifthey are involved, they should first berayed, and then remo^•ed surgically withthe associated gland chain, if that ispossible. If this is not possible, they shouldreceive surface radiation, and then beseeded with bare tubes of emanation, or. Fio. 4. Basal-celled epitnelioma. This is the type tnatcan usually be held in check but can rarely becured. radiation should be thorough, and littlethought may be given to the cosmeticresult. Surface radiation should be carriedout as for basal-celled epitheliomata, orsomewhat more intensively; and in addi-tion, unscreened tubes of emanation shouldbe seeded throughout the mass, usingapproximately one tube of to of tumor.
