Estrogen Receptor Positive Breast Cancer is a form of breast cancer that is caused by the increased sensitivity of certain protein structures present on the surface of the cancer cells to circulating estrogen in the body. These protein structures would stimulate the cancer cells to divide rapidly every time they come in contact with estrogen.
And so patients who are diagnosed with estrogen receptor positive breast cancer would need to undergo treatments and medications that aim at reducing the estrogen levels in the body, an action that would effectively prevent the division of the cancer cells.
