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