The treatment of choice in women with estrogen receptor-positive metastatic breast cancer (ER+ mBC) is classically divided into a variety of endocrine therapies, with three of the most common being: selective estrogen receptor modulators (SERM), aromatase inhibitors (AI), and selective estrogen receptor degraders (SERD).
What is the first-line treatment for breast cancer?
As mentioned above, the initial combination of medications for people with cancer that is positive for the estrogen or progesterone receptors depends on the occurrence of menopause. Chemotherapy may also be a first-line option for breast cancer that is not affected by hormonal therapy.

Summary of surgical options. To summarize, surgical treatment options include the following: Removal of cancer in the breast: Lumpectomy or partial mastectomy, generally followed by radiation therapy if the cancer is invasive. Mastectomy may also be recommended, with or without immediate reconstruction.
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.
How long can you take letrozole for metastatic cancer?
Most people are given letrozole for 5 years, but some will take it for up to 10 years.
Can I live 10 years with metastatic breast cancer?
What is the prognosis? While there is no cure for metastatic breast cancer, there are treatments that slow the cancer, extending the patient's life while also improving the quality of life, Henry says. Many patients now live 10 years or more after a metastatic diagnosis.

While treatable, metastatic breast cancer (MBC) cannot be cured. The five-year survival rate for stage 4 breast cancer is 22 percent; median survival is three years. Annually, the disease takes 40,000 lives.
Can metastatic breast cancer go into remission?
Metastatic breast cancer may never go away completely. But treatment can control its spread. Cancer may even go into remission at some points. This means you have fewer signs and symptoms of cancer.
What is the gold standard for breast cancer treatment?
Abstract. Tamoxifen is currently the endocrine treatment of choice for all stages of breast cancer and is the gold standard for antiestrogen treatment. Over the last 25 years, the drug has revolutionized breast cancer therapy.

The most common form of treatment for breast cancer is surgery. This involves removing the tumor and nearby margins. Surgical options may include a lumpectomy, partial mastectomy, radical mastectomy, and reconstruction.
Is chemotherapy necessary for stage 1 breast cancer?
Chemotherapy is not usually offered for stage 1 breast tumours. It may be offered after surgery (called adjuvant therapy) for these tumours if there is a high risk that the cancer will come back (recur). Find out more about the risk of breast cancer recurrence and adjuvant therapy.
What happens if you have ER positive breast cancer?
If you have ER-positive breast cancer, your cancer cells grow in the presence of the hormone estrogen. Estrogen occurs naturally in the body.
What to do if your doctor suspects breast cancer?
If your doctor suspects breast cancer, you will likely have a biopsy to test for cancerous cells. If there is cancer, your doctor will also test the cells for characteristics that include what receptors, if any, are present on the surface of the cancer cells.
What receptors interact with estrogen?
Hormone receptors can interact with estrogen or progesterone. Estrogen receptors are the most common. This is why ER-positive is the most common form of breast cancer. Some people are diagnosed with progesterone receptor-positive (PR-positive) breast cancer. The key difference is whether cancerous cells are getting growth signals from estrogen ...
What are the receptors in breast cancer?
In breast cancer, hormone receptors are the proteins located in and around breast cells. These receptors signal cells — both healthy and cancerous — to grow. In the case of breast cancer, the hormone receptors tell the cancer cells to grow uncontrollably, and a tumor results. Hormone receptors can interact with estrogen or progesterone.
What is estrogen receptor positive?
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. Most of these cases are ER-positive, meaning that there are estrogen receptors on the surface ...
What is the test for cancer recurrence?
The test examines 21 genes in cancerous tumors to identify the potential relapse rate. If you have a low recurrence score, you will likely not need chemotherapy. If you have a high recurrence score, you will likely need chemotherapy, surgery, and hormone therapy.
What does each number mean for breast cancer?
Each number reflects different characteristics of your breast cancer. These include the size of the tumor and whether cancer has moved into lymph nodes or distant organs, like the lungs, bones, or brain. The cancer subtype doesn’t play a role in staging, only in treatment decisions.
What is the treatment for estrogen receptor positive cancer?
Women with hormone receptor-positive (estrogen receptor-positive or progesterone receptor-positive) cancers are often treated first with hormone therapy (tamoxifen or an aromatase inhibitor). This may be combined with a targeted drug such as a CDK4/6 inhibitor, everolimus or a PI3K inhibitor.
What is the treatment for HER2 negative cancer?
HER2-negative cancers in women with a BRCA gene mutation. These women are typically treated with chemotherapy (and hormone therapy, if the cancer is hormone receptor-positive). An option after getting chemo is treatment with a targeted drug called a PARP inhibitor, such as olaparib or talazoparib.
What hormones are used for cancer?
For hormone receptor-positive (ER-positive or PR-positive) cancers that were being treated with hormone therapy, switching to another type of hormone therapy sometimes helps. For example, if either letrozole (Femara) or anastrozole (Arimidex) were given, using exemestane, possibly with everolimus (Afinitor), may be an option. Another option might be using fulvestrant (Faslodex) or an aromatase inhibitor (such as letrozole), along with a CDK inhibitor. If the cancer has a PIK3CA mutation and has grown while on an aromatase inhibitor, fulvestrant with alpelisib might be considered. If the cancer is no longer responding to any hormone drugs, chemotherapy is usually the next step.
What is the best treatment for bone metastases?
Treatment to relieve symptoms depends on where the cancer has spread. For example, pain from bone metastases may be treated with radiation therapy, drugs called bisphosphonates such as pamidronate (Aredia) or zoledronic acid (Zometa), or the drug denosumab (Xgeva).
What is radiation therapy?
Radiation therapy and/or surgery may also be used in certain situations, such as: When the breast tumor is causing an open wound in the breast (or chest) To treat a small number of metastases in a certain area, such as the brain.
