The influence of Ukrain on breast cancer was studied in ten women and monitored in each patient by clinical examination, mammography, ultrasonography, histopathology and immunofluorescence in the tissue material obtained after radical mastectomy performed ten days after discontinuation of the treatment. Observations accumulated during the study and analytical data support the view that Ukrain, by changing the antigenic expression of malignant cells, make them recognizable for the immune system which rejects them in a host-versus graft manner.
