THE effects on the incidence of spontaneous mammary carcinoma of breeding and of age in C3Hf mice have been recorded (Pullinger and Iversen, 1960). None of the tests done to detect the mammary tumour agent disclosed its presence in this strain (Pullinger, 1960a). A reduction in mammary tumour incidence in former breeding females after ovariectomy alone was reported (Pullinger, 1960b). In the present paper the incidence of mammary carcinoma and adenoma in C3Hf breeders after late ovariectomy with subsequent treatment with oestrone is described.
