RESUMO
The aim of this study is to investigate the presence of a possible association between breast and uterus cancer with blood ABO groups in women of reproductive, menopausal and post-menopausal age. Following information was recorded: patient age, stage of cancer, ABO blood group. In diseased population (120 subject) was investigated for ABO red cell blood groups antigens. Immunoserological methods have been used to identify the antigens. The obtained results were statistically processed. High frequency of A antigen is found in uterus cancer diseased, on the thirst stage, in the reproduction age (65±10,6%). High frequency of O antigen was found on the first stage, of the aid in the post-reproductive (55±11,1%) and in the postmenopausal periods (60±10,9%). ABO blood group antigens have been studied in breast cancer diseased, on the second and third stages, postmenopausal women, in which high frequency of A antigen is found.
