Breast cancer is a heterogeneous disease with multiple intrinsic tumor subtypes. These
subtypes vary in tumor gene expression and phenotype, and are most commonly grouped …

Aside from age, sex, and family history, risk of developing breast cancer is largely linked to
reproductive factors, which characterize exposure to sex hormones. Given that, molecular …

Background Associations between reproductive factors and breast cancer (BC) risk vary by
molecular subtype (ie, luminal A, luminal B, HER2, and triple negative/basal-like [TNBC]). In …

Abstract Background African American (AA) women have a disproportionately high
incidence of estrogen receptor–negative (ER-) breast cancer, a subtype with a largely …

Background Breast cancer comprises several molecular subtypes with different prognoses
and possibly different etiology. Reproductive and hormonal factors are associated with …

Multiple studies have found the neutrophil to lymphocyte ratio (NLR) to be associated with
adverse breast cancer (BC) prognosis and survival. Very limited data exist on the role of …

Background Limited evidence, mostly from studies in Western populations, suggests that the
prognostic effects of lifestyle-related risk factors may be molecular subtype-dependent. Here …

Background Breast cancer is the most common cancer in women worldwide. In the
Moroccan context, the role of well-known reproductive factors in breast cancer remains …

Background Reproductive factors have been shown to be differentially associated with risk
of estrogen receptor (ER)-positive and ER-negative breast cancer. However, their …
