What does hormone positive breast cancer mean? Hormone status of breast cancers includes: Estrogen receptor (ER) positive. The cells of this type of breast cancer have receptors that allow them to use the hormone estrogen to grow. Treatment with anti-estrogen hormone (endocrine) therapy can block the growth of the cancer cells.
What is the survival rate for hormone positive breast cancer?
|Stage at diagnosis||Percentage living after 5 years|
|localized (hasn’t spread outside the breast)||99 percent|
|regional (has spread to nearby tissue or lymph nodes)||86 percent|
|distant (has spread to distant organs)||28 percent|
|all stages combined||90 percent|
Are most breast cancers hormone positive? Hormone Receptor-Positive Breast Cancer
About 80% of all breast cancers are “ER-positive.” That means the cancer cells grow in response to the hormone estrogen. About 65% of these are also “PR-positive.” They grow in response to another hormone, progesterone.
Is it better to have estrogen positive or negative breast cancer? The survival rate for breast cancers are excellent if the cancer is detected early, and in general HR positive cancers grow slower and have a better prognosis. Overall, breast cancers that are both HR positive and HER2 negative have the best outcomes.
