ERBB is abbreviated from erythroblastic oncogene B, a gene originally isolated from the avian genome. The human protein is also frequently referred to as HER2 (human epidermal growth factor receptor 2) or CD340 (cluster of differentiation 340). [5] [6] [7] HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family ...
Women with a history of breast cancer have a higher chance of developing ovarian cancer, [1] vice versa. Breast cancer refers to the uncontrolled division of breast cells. It is possible for both males and females to get breast cancer. Breast cancer is the most common cancer women face. Ovarian cancer is a type of cancer which begins in the ...
Triple-negative breast cancer (TNBC) is any breast cancer that either lacks or shows low levels of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) overexpression and/or gene amplification (i.e. the tumor is negative on all three tests giving the name triple-negative).

The basal-like carcinoma is a recently proposed subtype of breast cancer defined by its gene expression and protein expression profile. [1]Breast cancer can be divided into five molecular subtypes, including luminal subtype A, luminal subtype B, normal breast-like subtype, HER-2 overexpression subtype, and basal-like subtype. [2]
HER2-positive tumors have a kind of receptor that allows the tumor to spread more quickly — or better respond to treatment. In all cases, the receptors can serve as clear targets for treatments.
Receptor status was traditionally considered by reviewing each individual receptor (ER, PR, her2) in turn, but newer approaches look at these together, along with the tumor grade, to categorize breast cancer into several conceptual molecular classes [46] that have different prognoses [39] and may have different responses to specific therapies. [47]
It is immunologically typically triple-negative, with negative estrogen receptors (ER), negative progesterone receptors (PR), and negative HER2/neu receptors. [3] There are also medullary breast carcinomas that are found to be estrogen receptors (ER) and/or progesterone receptor (PR) positive, making diagnosis less straightforward.
