How Does Endocrine Therapy Help Reduce The Recurrence Of Breast Cancer
Hormone-receptor-positive breast cancer depends on estrogen and progesterone to grow and spread. When these hormones are decreased in the body, the cancer cells cannot thrive. Endocrine Therapy stops the body from producing estrogen, and/or blocks cells from using the hormone to grow.
Endocrine therapy includes a few options. Depending on your circumstances Dr. Gorman may choose one of the following:
- Aromatase Inhibitors AIs stop the bodys tissues and organs from producing estrogen while allowing the ovaries to produce their natural amount. It is important that premenopausal women not use this therapy, as the drugs may increase production of estrogen in women who have not gone through menopause.
- Tamoxifen works in women who are both pre and postmenopausal by inhibiting cells to use estrogen, therefore decreasing and stopping growth.
- Ovarian Suppression stops the ovaries from producing estrogen through prescribed drugs or a surgical procedure. This option is for premenopausal women.

Cost And Health Insurance
The price of neoadjuvant therapy varies depending on the length of treatment needed and whether you have access to health insurance. For those with health insurance, the average cost is about $5,000.
Although NAT may cost thousands of dollars, most insurance companies cover these treatments. Also, successful neoadjuvant therapy will likely save you money in the long run by making more cost-effective treatment, like local removal of your breast cancer tumor, possible.
Starting With Neoadjuvant Therapy
Most often, these cancers are treated with neoadjuvant chemotherapy. For HER2-positive tumors, the targeted drug trastuzumab is given as well, often along with pertuzumab . This may shrink the tumor enough for a woman to have breast-conserving surgery . If the tumor doesnt shrink enough, a mastectomy is done. Nearby lymph nodes will also need to be checked. A sentinel lymph node biopsy is often not an option for stage III cancers, so an axillary lymph node dissection is usually done.
Often, radiation therapy is needed after surgery. If breast reconstruction is planned, it is usually delayed until after radiation therapy is done. For some, additional chemo is given after surgery as well.
After surgery, some women with HER2-positive cancers will be treated with trastuzumab for up to a year. Many women with HER2-positive cancers will be treated first with trastuzumab followed by surgery and then more trastuzumab for up to a year. If after neoadjuvant therapy, any residual cancer is found at the time of surgery, ado-trastuzumab emtansine may be used instead of trastuzumab. It is given every 3 weeks for 14 doses. For women with hormone receptor-positive cancer that is in the lymph nodes, who have completed a year of trastuzumab, the doctor might also recommend additional treatment with an oral targeted drug called neratinib for a year.

Side Effects Of Radiation Therapy
External beam radiation therapy is a non-invasive treatment with some short term and some longer-term side effects. Patients undergoing some weeks of treatment usually experience fatigue caused by the healthy tissue repairing itself and aside from this there can be no side effects at all. However many breast cancer patients develop a suntan-like change in skin color in the exact area being treated. As with a suntan, this darkening of the skin usually returns to normal in the one to two months after treatment. In some cases permanent changes in color and texture of the skin is experienced. Other side effects sometimes experienced with radiation can include:
- muscle stiffness
- tenderness in the area
After surgery, radiation and other treatments have been completed, many patients notice the affected breast seems smaller or seems to have shrunk. This is basically due to the removal of tissue during the lumpectomy operation.
The use of adjuvant radiation has significant potential effects if the patient has to later undergo breast reconstruction surgery. Fibrosis of chest wall skin from radiation negatively affects skin elasticity and makes tissue expansion techniques difficult. Traditionally most patients are advised to defer immediate breast reconstruction when adjuvant radiation is planned and are most often recommended surgery involving autologous tissue reconstruction rather than breast implants.
What Is An Axillary Ultrasound
This simple look at your axillary lymph nodes under your arm with ultrasound can often show if you will benefit from neoadjuvant or adjuvant chemotherapy. The goal is to identify any enlarged or suspicious appearing lymph nodes that may harbor breast cancer. Ask your breast surgeon to do this as a part of your examination. You can also ask for an order for an axillary ultrasound to be performed by a radiologist. This advance in breast cancer is rapidly being adopted by experienced breast surgeons and breast centers across the country. Review our short video lesson on Axillary Ultrasound to learn more about this cutting edge look into your breast cancer.

How Does Chemo Work For Breast Cancer
Chemotherapy for Breast Cancer. Chemotherapy uses anti-cancer drugs that may be given intravenously or by mouth. The drugs travel through the bloodstream to reach cancer cells in most parts of the body. Occasionally, chemo may be given directly into the spinal fluid which surrounds the brain and spinal cord.
Menstrual Changes And Fertility Issues
For younger women, changes in menstrual periods are a common side effect of chemo. Premature menopause and infertility may occur and could be permanent. If this happens, there is an increased risk of heart disease, bone loss, and osteoporosis. There are medicines that can treat or help prevent bone loss.
Even if your periods stop while you are on chemo, you may still be able to get pregnant. Getting pregnant while on chemo could lead to birth defects and interfere with treatment. If you have not gone through menopause before treatment and are sexually active, its important to discuss using birth control with your doctor. It is not a good idea for women with hormone receptor-positive breast cancer to take hormonal birth control , so its important to talk with both your oncologist and your gynecologist about what options would be best for you. When women have finished treatment , they can safely go on to have children, but it’s not safe to get pregnant while being treated.
If you think you might want to have children after being treated for breast cancer, talk with your doctor soon after being diagnosed and before you start treatment. For some women, adding medicines, like monthly injections with a luteinizing hormone-releasing hormone analog, along with chemo, can help them have a successful pregnancy after cancer treatment.

Sex Contraception And Pregnancy
If you havent been through the menopause, its important to use contraception because chemotherapy drugs can harm a developing baby in the first three months of pregnancy. Its still possible to become pregnant even if your periods become irregular or stop completely.
Your specialist will usually recommend barrier methods of contraception, such as condoms. The contraceptive pill is not usually recommended because it contains hormones. Emergency contraception such as the morning after pill can still be used.
An interuterine device can be used as long as its not the type that releases hormones. If you have a coil in place that does release hormones, such as the Mirena or Jaydess, when youre diagnosed, you may be advised to have this removed.

Will I Need Chemotherapy
Not everyone with early breast cancer will be recommended chemotherapy. Whether or not it is recommended for you will depend on your individual situation. Factors the doctors consider include the pathology of your breast cancer the risk of the cancer coming back or spreading to other parts of the body your general health and your preferences. Your medical oncologist will discuss whether chemotherapy is the right treatment for you and which combinations of medications are most appropriate.
Some aspects of your type of breast cancer can influence whether chemotherapy is recommended for you. Your surgeon or medical oncologist may talk to you about genomic tests. Genomic tests can help predict the likelihood of an individual cancer recurring and can provide information to help you decide whether you may benefit from chemotherapy or some other breast cancer treatments.
Your doctor may talk to you about genomic tests currently available, including:

Do I Already Have Cancer In My Axillary Nodes
If you are found to have lymph node positive breast cancer before surgery, it is likely you will benefit from neoadjuvant chemotherapy. Your breast surgeons exam is not always successful at identifying breast cancer in the axillary lymph nodes under the arm. Request an axillary ultrasound from your breast surgeon while you are in the examination room. You want to know early on whether cancer is suspected to have spread to your lymph nodes. Take our video lesson on Axillary Ultrasound . You can have a minimally invasive needle biopsy to see if the abnormal node has cancer within it. If so, it opens the door for more sophisticated treatment options including neoadjuvant chemotherapy.
Why Does Breast Cancer Treatment Always Include Chemotherapy
This type of cancer is typically treated with chemotherapy before a mastectomy, followed by radiation, to decrease the chance of recurrence. If your breast cancer has spread to other parts of your body, radiation therapy may be recommended to shrink the cancer and help control symptoms such as pain.

Breast Reconstruction After Surgery
Many woman having surgery for breast cancer might have the option of breast reconstruction. A woman having a mastectomy might want to consider having the breast mound rebuilt to restore the breasts appearance after surgery. In some breast-conserving surgeries, a woman may consider having fat grafted into the affected breast to correct any dimples left from the surgery. The options will depend on each womans situation.
There are several types of reconstructive surgery, but your options depend on your medical situation and personal preferences. You may have a choice between having breast reconstruction at the same time as the breast cancer surgery or at a later time .
If you are thinking about having reconstructive surgery, its a good idea to discuss it with your breast surgeon and a plastic surgeon before your mastectomy or BCS. This gives the surgical team time to plan out the treatment options that might be best for you, even if you wait and have the reconstructive surgery later.

Dr. Moo worked closely with Kéaras medical oncologist, , and radiation oncologist, Michael Bernstein, to ensure each aspect of her care went smoothly. All three practice at MSK Nassau.
We all are down the hall from each other, says Dr. Moo. I remember Dr. Brockway-Marchello coming to my office, saying, Hey, Kéaras having this dramatic response to the chemo. We always communicate while our patients are being treated so that we are always on the same page.
Dr. Moo was also a trusted source of information about COVID-19, Kéara says. She was hesitant about getting vaccinated but decided to do so after talking about it with Dr. Moo.
Kéara says, There was this comfort of being able to speak to her and have her ease my concerns that I thought, OK, Im going to get it.

Search Methods For Identification Of Studies
The Specialised Register maintained by the Cochrane Breast Cancer Group was searched on 4th August 2005 trials and applies no language restrictions. We performed two searches, one to identify references which were coded in the specialised register as “early” and “chemo”, and a second to identify those references that had been assigned the CBCG codes “locally advanced” and “chemo”. In addition, we searched the reference lists of other related literature reviews .
Is Chemotherapy Necessary Before And After Having A Mastectomy
When it comes to treating breast cancer, many people have questions about treatment options. Does a patient need chemotherapy before or after they have a mastectomy?
For most patients, the mastectomy is performed first and is followed by chemotherapy or other suitable treatments. But some patients have better success if that order is reversed and they receive chemotherapy before their surgery. It is important to discuss these options with your doctor or surgeon to find out which they recommend for optimal results.

- PERJETA should not be used in patients who are allergic to pertuzumab or to any of the ingredients in PERJETA
- Infusion-related reactions: PERJETA is a medicine that is delivered into a vein through a needle. PERJETA has been associated with infusion-related reactions, some fatal. The most common infusion-related reactions when receiving PERJETA, Herceptin, and docetaxel were feeling tired, abnormal or altered taste, allergic reactions, muscle pain, and vomiting. The most common infusion-related reactions when receiving PERJETA alone were fever, chills, feeling tired, headache, weakness, allergic reactions, and vomiting
- Severe allergic reactions: Some people receiving PERJETA may have severe allergic reactions, called hypersensitivity reactions or anaphylaxis, which may happen quickly and may affect many areas of the body. Severe allergic reactions, some fatal, have been observed in patients treated with PERJETA
What Is Chemotherapy
Chemotherapy is a treatment that destroys cancer cells using anti-cancer drugs. It works by interfering with the cancer cells ability to divide and grow.
Different chemotherapy drugs work in different ways. This is why a combination of drugs is often used.
Chemotherapy affects cells throughout the body and can cause side effects.

What Is A Mastectomy
A mastectomy is a surgical procedure that removes the entire breast. The procedure includes a total mastectomy, where all the breast tissue is removed, but the nipple is left. This procedure is performed to help remove cancerous tissue. The type of mastectomy a patient has depends on the severity of the cancer diagnosis.

ON THIS PAGE: You will learn about the different types of treatments doctors use for people with breast cancer. Use the menu to see other pages.
This section explains the types of treatments that are the standard of care for early-stage and locally advanced breast cancer. Standard of care means the best treatments known. When making treatment plan decisions, you are strongly encouraged to consider clinical trials as an option. A clinical trial is a research study that tests a new approach to treatment. Doctors want to learn whether the new treatment is safe, effective, and possibly better than the standard treatment. Clinical trials can test a new drug and how often it should be given, a new combination of standard treatments, or new doses of standard drugs or other treatments. Some clinical trials also test giving less treatment than what is usually done as the standard of care. Clinical trials are an option to consider for treatment and care for all stages of cancer. Your doctor can help you consider all your treatment options. Learn more about clinical trials in the About Clinical Trials and Latest Research sections of this guide.

Prompt Surgery Is Better
Because Im a surgeon Ill take a look at Bleicher et al first. This study looks at two large cancer databases, the Surveillance, Epidemiology, and End Results -Medicarelinked database and the National Cancer Database . The SEER-Medicare cohort included Medicare patients older than 65 years, and the NCDB cohort included patients cared for at Commission on Canceraccredited facilities throughout the United States. Analyses performed assessed overall survival as a function of time between diagnosis and surgery and evaluated five intervals . It also looked at disease-specific survival at 60 day intervals. The patient cohort included women diagnosed with invasive breast cancer that had not metastasized beyond axillary lymph nodes who were treated with surgery first. Patients with inflammatory breast cancer were excluded, which makes sense because inflammatory cancer is generally treated first with chemotherapy. The SEER-Medicare cohort included 94,544 patients 66 years or older diagnosed between 1992 and 2009, while the NCDB cohort included 115,970 patients 18 years or older diagnosed between 2003 and 2005.
The tale is told by this graph, from the SEER-Medicare cohort and the NCDB cohort :

Procedures Required Prior To Neoadjuvant Chemotherapy
In order to be able to accurately assess the status of the response to therapy, it is critically important to have a definitive diagnosis of breast cancer and obtain information about tumor type, tumor grade, presence or absence of necrosis, and/or lymphatic and vascular invasion.30 This information is helpful in making decisions about the initiation of neoadjuvant chemotherapy and selection of medication. A clip should be placed at the time of initial tissue sampling or during the first few cycles of neoadjuvant chemotherapy. This will make it possible to reliably identify the tumor bed after therapy. Access to sufficient tumor tissue is also required to be able to assess the status of biomarkers such as hormone receptors and HER2/neu oncogene. In addition, the status of axillary lymph nodes has to be known, clinically and by imaging, prior to neoadjuvant chemotherapy. Clinically positive axillary lymph nodes should be sampled by minimally invasive procedures such as fine needle aspiration biopsy and/or core needle biopsy. Clinically negative axillary lymph nodes should be sampled by sentinel lymph node biopsy.3133
