The relationship between sensitivity, breast nursing, brain laterality and risk of breast cancer is controverse in the literature. In order to clarify whether these parameters are related to the presence of breast cancer, we assessed 100 following women with this neoplasm. Most of women were white (61%), followed by black (30%) and coloured (9%). Previous pregnancies were related by 75% of patients, but 62 women had abortions. Breast nursing was affered by 66 of them, that preferred to nurse by the left breast (25), right breast (13) or indifferently (28). This preference is related to comfort. A relation between side of the cancer and breast sensitivity seems to occur. In conclusion, multiple pregnancies, long period-nursing or brain laterality did not protect women against breast cancer.
