The luminal typing of breast cancer is called molecular typing, which has a greater role in the treatment and prognosis of breast cancer. luminal typing is divided into four main types: the first type, luminal A, is estrogen and progesterone receptor positive, but HER-2 negative, called luminal A, which can be treated with endocrine therapy, but not with targeted therapy. The second type, luminalB, is positive for both estrogen and progesterone and HER-2, and can be used for endocrine therapy, chemotherapy and targeted therapy, with relatively good treatment effect. The third type, HER-2 positive, estrogen and progesterone receptor are negative, this treatment effect is not too good, for endocrine therapy is not effective, can use targeted therapy. The fourth type, negative for both estrogen and progesterone receptors and HER-2, has the worst therapeutic effect.
