What does luminal mean in breast cancer?

Luminal A breast cancer is hormone-receptor positive (estrogen-receptor and/or progesterone-receptor positive), HER2 negative, and has low levels of the protein Ki-67, which helps control how fast cancer cells grow. Luminal A cancers are low-grade, tend to grow slowly and have the best prognosis.

Is luminal A breast cancer invasive?

Invasive breast cancers are classified by morphology: ductal, lobular, tubular, mucinous, medullary, papillary, metaplastic, and others. Breast cancer subtypes are determined by gene profiling: luminal A, luminal B, normal, HER2+, and basal-like.
