[Diagnostic accuracy of malignancy risk index II in post-menopausal women with adnexal tumours].

Background: The purpose of the diagnostic evaluation of adnexal tumours is to exclude the possibility of malignancy. The malignancy risk index II identifies patients at high risk for ovarian cancer. The cut-off value is greater than 200.

The effect of insulin resistance on breast cancer risk in Latinas of Mexican origin.

Background: Conclusive evidence has yet to emerge regarding the association between markers of hyperinsulinemia and breast cancer. We determined the effect of insulin resistance (IR) on breast cancer risk in Latinas of Mexican origin who did not have a direct family history of breast cancer and had not been previously diagnosed with prediabetes or diabetes.

Methods: This was a case-control study in which a case (n=124) was defined as a patient with a recent histopathologic diagnosis of breast cancer and a control (n=197) was defined as a participant who had recently undergone a mammography and had either a Breast Imaging, Reporting & Data System (BI-RADS)-1 or a BI-RADS-2 score.

Prediabetes, diabetes, and risk of breast cancer: a case-control study.

Background And Aims: Although underlying mechanisms have been described to account for the association between prediabetes and diabetes with breast cancer, reported results have been inconsistent. We undertook this study to determine whether prediabetes and diabetes are risk factors for breast cancer in Mexican women with no family history of breast cancer in the mother, daughters, or sisters.

Methods: A case-control study was carried out during 2011-2013.
