| Abstract: | In reviewing and summarizing work at our institution, we have identified some surprising consistencies in patients with breast cancer. Breast cancer shows four features of cerebral laterality: excess left-handedness, atypical season-of-birth patterns, the risk factor of advanced maternal age, and an association with prenatal sex hormones. Since hypopigmentation also relates to cerebral laterality, a consequence of the association of breast cancer and cerebral laterality is that eye color should be measured as a function of side of disease and age at diagnosis in women with breast cancer. |
