What does it mean when they tell me my tumor is estrogen receptive?
A cancer is called estrogen-receptor-positive (or ER+) if it has receptors for estrogen. This suggests that the cancer cells, like normal breast cells, may receive signals from estrogen that could promote their growth. The cancer is progesterone-receptor-positive (PR+) if it has progesterone receptors.
What cancers are estrogen receptive?
Estrogen receptor-positive (ER-positive) breast cancer is the most common type of breast cancer diagnosed today. According to the American Cancer Society, about 2 out of every 3 cases of breast cancer are hormone receptor-positive.
What does ER and PR positive mean?
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.
What does ER and PR negative mean?
Hormone receptor-negative breast cancer cells don’t have receptors for either estrogen (ER) or progesterone (PR). This means the cancer cells don’t grow in response to hormones. Hormone receptor-negative breast cancer accounts for about 25 to 30 percent of breast cancers.
Why is hormone therapy recommended?
Hormones help certain types of breast, prostate, and some other cancers to grow. If you have one of them, your doctor may recommend hormone therapy to slow the cancer’s growth or stop it from spreading. Hormone therapy is also called hormonal therapy, hormone treatment, or endocrine therapy.
Is a high Allred score good?
Tumours with a histoscore of 50 or more are usually considered HR positive. Additionally, the Allred scoring system has been used, which is a semi-quantitative measure that takes into consideration the proportion of positive cells (scored on a scale of 0–5) and staining intensity (scored on a scale of 0–3).
What happens when hormone therapy stops working?
When hormone therapy stops working In some cases this can cause the cancer to shrink and stop growing for some time. This is called anti androgen withdrawal response (AAWR). There are different treatment options for when hormone therapy stops working, such as chemotherapy or steroids.
Does hormone therapy weaken immune system?
Hormone therapies, including tamoxifen, letrozole, anastrozole, exemestane and goserelin, do not affect your risk of getting coronavirus or of becoming seriously ill if you do get it. Taking hormone therapy does not affect your immune system.
How do I stop taking hormone therapy?

- reduce estrogen daily dosage to next lower level every 2-4 weeks until the lowest dosage is reached.
- if symptoms of lower estrogen become significant, then maintain current dosage for several weeks and, if necessary, increase to next highest dosage for 2-4 weeks.
What happens when you go off hormone replacement therapy?
