What does ER positive mean?
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. Progesterone receptor (PR) positive.
Can ER-positive breast cancer be cured?
ER-positive breast cancer has a high chance of being successfully treated, especially when it's discovered early. A diagnosis at a later stage will have a less positive outlook, but being diagnosed at a later stage is less common. There are still many treatment options for late stage cancer.
Is chemo necessary for ER-positive?
Most instances of ER-positive, HER2-negative, node-negative breast cancer <1 cm, and all cancers ≤0.5 cm, have a sufficiently good prognosis with endocrine therapy alone, that they do not typically require adjuvant chemotherapy.
What is considered ER-positive breast cancer?
Guidelines for the use of chemotherapy and endocrine therapy recently recommended that estrogen receptor (ER) status be considered positive if ≥1% of tumor cells demonstrate positive nuclear staining by immunohistochemistry. In clinical practice, a range of thresholds are used; a common one is 10% positivity.
What happens if ER PR is positive?
If breast cancer cells have estrogen receptors, the cancer is called ER-positive breast cancer. If breast cancer cells have progesterone receptors, the cancer is called PR-positive breast cancer. If the cells do not have either of these 2 receptors, the cancer is called ER/PR-negative.
Is it better to be ER PR positive or negative?
Tumors that are ER/PR-positive are much more likely to respond to hormone therapy than tumors that are ER/PR-negative. You may have hormone therapy after surgery, chemotherapy, and radiation are finished. These treatments can help prevent a return of the disease by blocking the effects of estrogen.
Is it better to have a mastectomy rather than a lumpectomy?
Lumpectomy and mastectomy procedures are both effective treatments for breast cancer. Research shows there is no difference in survival rate from either procedure, though lumpectomy has a slightly higher risk of recurrent cancer.
What is the deadliest form of breast cancer?
Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it's found, and is more likely to come back after treatment than other types of breast cancer.

Rare types of invasive ductal carcinoma It occurs when cancer cells within the milk duct of the breast produce mucous, which also contains breast cancer cells. The cells and mucous combine to form a tumor. Pure mucinous ductal carcinoma tends to grow slowly, and has a better prognosis than some other types of IDCs.
How much does letrozole reduce risk of recurrence?
There was also a statistically significant 26% reduction in breast cancer–free interval events (3% absolute improvement) and a statistically significant 29% reduction in distant recurrences (1.8% absolute improvement) with letrozole, Dr. Mamounas reported at the 2019 San Antonio Breast Cancer Symposium.
Is invasive ductal carcinoma aggressive?
The five-year survival rate for localized invasive ductal carcinoma is high — nearly 100% when treated early on. If the cancer has spread to other tissues in the region, the five-year survival rate is 86%. If the cancer has metastasized to distant areas of your body, the five-year survival rate is 28%.
What's the difference between tamoxifen and letrozole?
Hormone therapy using letrozole may fight breast cancer by reducing the production of estrogen. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. If is not yet known which treatment regimen is most effective for breast cancer.
What is ER positive breast cancer?
What is ER-positive breast cancer? Of the 250,000 new cases of breast cancer diagnosed in the United States each year, 70% are ER-positive, meaning their cells bear a receptor for the estrogen hormone, which drives the growth and proliferation of breast tumors.
How much of breast cancer is inherited?
An inherited gene accounts for 8-10% of ER-positive breast cancer, although their treatment is the same as for non-hereditary cases.
How long does endocrine therapy last?
Endocrine therapy for five to 10 years, to prevent metastatic disease, recurrence, and tumors in the opposite breast, is recommended for almost all patients with ER-positive breast cancer.
Is endocrine therapy a metastatic disease?
Endocrine therapy is also standard treatment for metastatic disease. All the endocrine therapies carry some risks and have side effects. Burstein’s review notes that better understanding of these side effects and how to manage them can help providers individualize therapy for patients.
Is there a sea change in breast cancer treatment?
Immunotherapy. Burstein says there has been a “sea change” in the use of chemotherapy for early-stage ER-positive breast cancer, thanks to tests of the genomic characteristics of a tumor and which “allow the majority of women to avoid chemotherapy.”.
What is the main indicator of potential responses to endocrine therapy (ET), and approximately 70% of breast cancers

How to prevent breast cancer recurrence?
Preventive surgery. Before menopause, a doctor may suggest surgery to remove the ovaries. Undergoing this procedure can lower estrogen levels in the body and may help prevent a recurrence of breast cancer. However, this is an invasive treatment that can have a considerable impact on a person’s life.
What receptors are most common in breast cancer?
In ER-positive breast cancer, cancerous cells receive their growth signals from the hormone estrogen. Estrogen receptors are the most common type of hormone receptor on breast cells.
What are the two types of breast cancer?
Two types of hormone receptor-positive breast cancer are estrogen receptor-positive (ER-positive) breast cancer and progesterone receptor-positive (PR-positive) breast cancer. In these cancers, the cancer cells receive their growth signals from estrogen and progesterone, respectively. When the growth of cancer cells results from problems ...
Why do breast cancers develop?
Some breast cancers develop due to a problem involving hormones, including estrogen and progesterone. These hormones play a role in telling breast cells to grow. In hormone receptor-positive breast cancer, the receptors for hormones cause breast cells to grow in an uncontrolled way. Two types of hormone receptor-positive breast cancer are estrogen ...
What is it called when a cancer cell is not involved in hormone receptors?
When hormones are not involved, it is called hormone receptor-negative breast cancer . This article focuses on ER-positive breast cancer, including its risk factors, symptoms, diagnosis, and treatment.
What are the factors that increase the risk of breast cancer?
the risk include excessive alcohol consumption, a high body mass index ( BMI) in early life, obesity after menopause, and a lack of physical activity. These may all increase exposure to breast cancer related hormones.

How big is a stage 3 breast tumor?
In stage III breast cancer, the tumor is large (more than 5 cm or about 2 inches across) or growing into nearby tissues (the skin over the breast or the muscle underneath), or the cancer has spread to many nearby lymph nodes.
Can stage 3 breast cancer spread to lymph nodes?
If you have inflammatory breast cancer: Stage III cancers also include some inflammatory breast cancers that have not spread beyond near by lymph nodes. Treatment of these cancers can be slightly different from the treatment of other stage III breast cancers.
Can you get radiation therapy before mastectomy?
If you were initially diagnosed with stage II breast cancer and were given treatment such as chemotherapy or hormone therapy before surgery, radiation therapy might be recommended if cancer is found in the lymph nodes at the time of the mastectomy.
Can you get a mastectomy with a large breast?
For women with fairly large breasts, BCS may be an option if the cancer hasn’t grown into nearby tissues. SLNB may be an option for some patients, but most will need an ALND.

Trastuzumab and hyaluronidase (Herceptin Hylecta) is another type of trastuzumab treatment that is injected underneath the skin. Pertuzumab (Perjeta) treats HER2-positive early breast cancer, usually in combination with trastuzumab and chemotherapy. It’s FDA-approved for neoadjuvant and adjuvant treatment.
How long does it take for estrogen to work after breast cancer surgery?
One day you’ll get the treatment, and then you’ll wait 14 or 21 days for the next treatment. This gives your body a chance to recover from the side effects. As an adjuvant therapy, expect to start within 4 to 6 weeks of surgery. Endocrine therapy. More than half of breast cancers feed on estrogen to grow.
What is the HER2 subtype?
About one in five people with breast cancer have the HER2+ subtype. If your breast cancer is of the HER2+ subtype, your tumor has high levels of a protein called human epidermal growth factor receptor 2 (HER2). HER2 plays a role in the growth of cancer cells, which is why HER2+ breast cancer tends to be aggressive.

How to treat hormone sensitive breast cancer?
Several strategies are used to treat hormone-sensitive breast cancer: Blocking ovarian function: Because the ovaries are the main source of estrogen in premenopausal women, estrogen levels in these women can be reduced by eliminating or suppressing ovarian function. Blocking ovarian function is called ovarian ablation.
What is a breast tumor that has estrogen and/or progesterone receptors called?
Breast tumors that contain estrogen and/or progesterone receptors are sometimes called hormone receptor positive (HR positive). Most ER-positive breast cancers are also PR positive.

What type of cancer is adjuvant hormone therapy?
Decisions about the type and duration of adjuvant hormone therapy are complicated and must be made on an individual basis in consultation with an oncologist. Treatment of advanced or metastatic breast cancer: Several types of hormone therapy are approved to treat metastatic or recurrent hormone-sensitive breast cancer.
How do you know if breast cancer cells contain hormone receptors?
To determine whether breast cancer cells contain hormone receptors, doctors test samples of tumor tissue that have been removed by surgery.
Can hormones be used for breast cancer?
Tumors that are hormone insensitive do not have hormone receptors and do not respond to hormone therapy. Hormone therapy for breast cancer should not be confused with menopausal hormone therapy (MHT)—treatment with estrogen alone or in combination with progesterone to help relieve symptoms of menopause. These two types of therapy produce opposite ...
Does hormone therapy affect breast cancer?
These two types of therapy produce opposite effects: hormone therapy for breast cancer blocks the growth of HR-positive breast cancer, whereas MHT can stimulate the growth of HR-positive breast cancer. For this reason, when a woman taking MHT is diagnosed with HR-positive breast cancer she is usually asked to stop that therapy.
What is the role of HER2 in breast cancer?
Human epidermal growth factor receptor-2 (HER2) is a protein that promotes cell growth and HER2 positive breast cancers have a higher than normal presence of these proteins, because of mutations in HER2 gene. Triple negative cancers account for approximately 15% of breast cancers.
What is the procedure to remove breast cancer?
Mastectomy: Removal of the whole breast if the cancer has spread to other breast tissue. Lymphadenectomy: Removal of sentinel lymph nodes, where the cancer is likely to spread first, and/or the lymph nodes under the arm, to test for cancer.
What is PARP inhibitor?
PARP inhibitors: PARP inhibitors are used to treat triple negative, as well as HR positive and HER2 negative breast cancers which have BRCA mutations. Poly ADP ribose polymerase (PARP) is an enzyme that helps DNA repair, and PARP inhibitors block the cancer cells from repairing their DNA so they die.
What is hormone therapy?
Hormone therapy is used as an adjuvant therapy after surgery, to reduce risk of cancer recurrence and to stop or slow down cancer growth in metastatic cancer. Hormone therapy is used only for breast cancers that are HR positive. The types of medications used in hormone therapy include:
Why do we need hormone therapy for breast cancer?
Hormone therapy is usually given after breast cancer treatment to reduce the risk of recurrence. Hormone therapy reduces estrogen levels in the body or blocks the activity of estrogen receptors on the cancer cells. Cancers are a group of diseases in which some types of cells turn abnormal and proliferate without control.
What is the difference between stage 2 and stage 3 breast cancer?
Stage II: The tumor has grown and spread to a few nearby lymph nodes. Stage III: The tumor has grown into many lymph nodes and other tissue in the breast. Stage IV: The cancer has spread (metastatic cancer) to distant parts of the body.
What percentage of breast cancer is triple negative?
Triple negative cancers account for approximately 15% of breast cancers. Triple negative breast cancer more often occurs in African-American women younger than 40, or women who have an inherited mutation in BRCA1 gene, which normally is a tumor suppressor gene, which suppresses cell growth.
