[Relationship between the number of mast cells and neoplastic prolideration of the mammary gland epithelium].

The results of the experiments make it possible to regard the number of mast in mammary glands as an index correlating with the intensity of the proliferative reaction of the mammary gland epithelium reflecting the course of the pathological process in the tissue. This index is higher to the moment of benign tumor formation. The second more intensive rise of this index characterizes malignant transformation of the epithelium. A decrease of the mast cells level since the moment of malignant transformation and their rather low content in malignant tumors manifest the decompensation of the organism antiblastic system.
