Epub 2021 Sep 10. hall county inmate list There are numerous reports that the general risk of developing cancer in the breast parenchyma is elevated among women with complex fibroadenomas; these women are 3.1-3.7 times more likely to develop breast cancer than women in the general population (compared with a relative risk of 1.9 times in women with non-complex fibroadenomas). Patients with complex lesions were 18.5 years older (median age, 47 years; range, 21-69 years) than patients with noncomplex fibroadenomas (median age, 28.5 years; range, 12-86 years) (p < 0.001). However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA).
