What does receptor mean in breast cancer?

There are three main types of breast cancer cells: hormone-sensitive, HER2-positive, and triple-negative. These cells all respond differently to hormone treatments, Her2-positive breast cancer cells typically respond best to drugs called HER2 inhibitors, while hormone-sensitive breast cancer cells respond best to anti-estrogen drugs. Triple-negative breast cancer cells do not have any of these three receptors, and as a result, are less likely to respond to these treatments.

What does receptors mean in breast cancer growth?

Hormone receptors are proteins located on the surface of cancer cells. They act as a signal to the cancer cell that the particular hormone it is dependent on is present. If that hormone is not present, the cell does not grow. Hormone receptors can be categorized by their location on the cell membrane. Any receptor that is located on the cell membrane is categorized as a “membrane-bound receptor.” There are also hormone receptors that are located inside the cell. These receptors

What does the receptors mean in breast cancer?

There are several different types of receptors: estrogen receptors (ER), progesterone receptors (PR), and human epidermal growth factor receptor 2 (HER2). About two-thirds of breast cancers have a positive ER status. This means that the cancer cells contain the ER protein that allows them to respond to estrogen, which plays an important role in the development of the breast. Approximately one-third of breast cancers have a negative ER status. These cancers are not able to respond to estrogen as normal

What does receptors mean in breast cancer test?

A breast cancer test can determine how much cancer cells are growing in the breast. The results of a cancer test—called a biopsy—are evaluated to determine the cancer’s stage and type (which is referred to as the “tumor” classification). A biopsy can also help your healthcare provider determine the type of breast cancer you have and whether it’s treatable.
