Common questions about breast cancer treatment
Learn more from breast surgeon Judy C. Boughey, M.D.
Definitely, you should always discuss your personal preferences in terms of your goals for treatment with your health care team. This will help your team come up with the best treatment plan for you. We need to know whether you have limited time off work. We need to know whether it's more important for you that everything is accomplished at one operation, or whether you're open to having two operations in order to have the best long-term cosmetic outcome. All of these nuances in terms of travel distance, your fears about radiation, your fears about chemotherapy, your fears about surgery are important so that your health care team can put your mind at rest and can also dispel any potential myths that you may have that may be inaccurate.
This is a very common question that I get. And essentially the answer is no. Cancer does not spread or jump from one breast to the other breast. If a patient with breast cancer develops a subsequent breast cancer on the contralateral side or on the other side. This is usually a "de novo" or a new primary breast cancer, and it's very unlikely for a single breast cancer to spread from one side to the other.
No, the needle biopsy is commonly performed and this does not increase the chance of spreading of the breast cancer.
Well, there have been a lot of advances in both breast surgical options and reconstructive options. In terms of breast surgery, increasingly, women have the option of breast-conserving surgery, allowing them to maintain their normal breast. For those women who do need to undergo mastectomy, we now have more options in terms of how that mastectomy is performed. And for some women, we are able to preserve the nipple and areola complex at the time of their mastectomy so that their reconstructed breast mound has their normal skin and their normal nipple and areola complex. In terms of breast reconstruction, increasingly that reconstruction is performed in front of the muscle, minimizing the muscle spasm and some of the pain associated with that after reconstructive surgery.
Well, here at Mayo Clinic, we have a strong multidisciplinary team. Usually your first portal of entry is our breast clinic. This is a group of internal medicine boarded physicians specializing in breast care. And they can see you, evaluate your imaging and pathology and discuss all of the findings with you before they then refer you on to breast surgery, breast medical oncology and breast radiation. For patients with more advanced disease, where upfront medical therapy prior to surgery is likely to be recommended, you'll be seen as part of our multidisciplinary team, where you'll meet with both the surgeon, the medical oncologist, and the radiation oncologist on the same day. In terms of surgery, we have strong support from our pathologists with our frozen section pathology. This means, for women undergoing breast-conserving surgery, where we are removing just the breast cancer or the lump, also called a lumpectomy, our pathologists will actually evaluate the edges of that lumpectomy during surgery. And if there's any disease at an edge then we will re-excise that edge or that margin during that same operation. This means that the chances of needing a second operation to clear those margins is as low as about 3%, as in fact has been shown to be four-fold lower than any other institution.
The best way to partner with your medical team is to be completely honest about everything that you're taking or doing and your own personal preferences. Many people are often drinking alcohol or smoking and even the use of herbal supplements. And it's really important that your health care team is aware of all of these behaviors. Smoking can definitely impact some of the potential options in terms of reconstruction, if you choose a mastectomy. And even herbal supplements can sometimes interact with some of the medical therapies. So be transparent and discuss everything openly with your medical team, so that together you can come up with the best treatment plan.
I recommend working closely with a multidisciplinary team specialized in the care of breast cancer. Look at all of the treatment options and plan your journey with your multidisciplinary team and include your family and friends. And remember, as you embark on this journey and go through this journey, there are thousands of women out there that have successfully completed this journey, decades out from their breast cancer diagnosis, living full lives.
Diagnosing breast cancer
Core needle biopsy
A core needle biopsy uses a long, hollow tube to obtain a sample of tissue. Here, a biopsy of a suspicious breast lump is being done. The sample is sent to a laboratory for testing and evaluation by doctors who specialize in analyzing blood and body tissue (pathologists).
During a breast MRI, you lie on your stomach on a padded scanning table. Your breasts fit into a hollow depression in the table, which contains coils that detect magnetic signals. The table slides into the large opening of the MRI machine.
Tests and procedures used to diagnose breast cancer include:
- Breast exam. Your doctor will check both of your breasts and lymph nodes in your armpit, feeling for any lumps or other abnormalities.
- Mammogram. A mammogram is an X-ray of the breast. Mammograms are commonly used to screen for breast cancer. If an abnormality is detected on a screening mammogram, your doctor may recommend a diagnostic mammogram to further evaluate that abnormality.
- Breast ultrasound. Ultrasound uses sound waves to produce images of structures deep within the body. Ultrasound may be used to determine whether a new breast lump is a solid mass or a fluid-filled cyst.
Removing a sample of breast cells for testing (biopsy). A biopsy is the only definitive way to make a diagnosis of breast cancer. During a biopsy, your doctor uses a specialized needle device guided by X-ray or another imaging test to extract a core of tissue from the suspicious area. Often, a small metal marker is left at the site within your breast so the area can be easily identified on future imaging tests.
Biopsy samples are sent to a laboratory for analysis where experts determine whether the cells are cancerous. A biopsy sample is also analyzed to determine the type of cells involved in the breast cancer, the aggressiveness (grade) of the cancer, and whether the cancer cells have hormone receptors or other receptors that may influence your treatment options.
- Breast magnetic resonance imaging (MRI). An MRI machine uses a magnet and radio waves to create pictures of the interior of your breast. Before a breast MRI, you receive an injection of dye. Unlike other types of imaging tests, an MRI doesn't use radiation to create the images.
Other tests and procedures may be used depending on your situation.
Staging breast cancer
Once your doctor has diagnosed your breast cancer, he or she works to establish the extent (stage) of your cancer. Your cancer's stage helps determine your prognosis and the best treatment options.
Complete information about your cancer's stage may not be available until after you undergo breast cancer surgery.
Tests and procedures used to stage breast cancer may include:
- Blood tests, such as a complete blood count
- Mammogram of the other breast to look for signs of cancer
- Breast MRI
- Bone scan
- Computerized tomography (CT) scan
- Positron emission tomography (PET) scan
Not all women will need all of these tests and procedures. Your doctor selects the appropriate tests based on your specific circumstances and taking into account new symptoms you may be experiencing.
Breast cancer stages range from 0 to IV with 0 indicating cancer that is noninvasive or contained within the milk ducts. Stage IV breast cancer, also called metastatic breast cancer, indicates cancer that has spread to other areas of the body.
Breast cancer staging also takes into account your cancer's grade; the presence of tumor markers, such as receptors for estrogen, progesterone and HER2; and proliferation factors.
Your doctor determines your breast cancer treatment options based on your type of breast cancer, its stage and grade, size, and whether the cancer cells are sensitive to hormones. Your doctor also considers your overall health and your own preferences.
Most women undergo surgery for breast cancer and many also receive additional treatment after surgery, such as chemotherapy, hormone therapy or radiation. Chemotherapy might also be used before surgery in certain situations.
There are many options for breast cancer treatment, and you may feel overwhelmed as you make complex decisions about your treatment. Consider seeking a second opinion from a breast specialist in a breast center or clinic. Talk to other women who have faced the same decision.
Breast cancer surgery
A lumpectomy involves removing the cancer and some of the healthy tissue that surrounds it. This illustration shows one possible incision that can be used for this procedure, though your surgeon will determine the approach that's best for your particular situation.
During a total (simple) mastectomy, the surgeon removes the breast tissue, nipple, areola and skin. Other mastectomy procedures may leave some parts of the breast, such as the skin or the nipple. Surgery to create a new breast is optional and can be done at the same time as your mastectomy surgery or it can be done later.
Sentinel node biopsy
Sentinel node biopsy identifies the first few lymph nodes into which a tumor drains. The surgeon uses a harmless dye and a weak radioactive solution to locate the sentinel nodes. The nodes are removed and tested for signs of cancer.
External beam radiation uses high-powered beams of energy to kill cancer cells. Beams of radiation are precisely aimed at the cancer using a machine that moves around your body.
Operations used to treat breast cancer include:
Removing the breast cancer (lumpectomy). During a lumpectomy, which may be referred to as breast-conserving surgery or wide local excision, the surgeon removes the tumor and a small margin of surrounding healthy tissue.
A lumpectomy may be recommended for removing smaller tumors. Some people with larger tumors may undergo chemotherapy before surgery to shrink a tumor and make it possible to remove completely with a lumpectomy procedure.
Removing the entire breast (mastectomy). A mastectomy is an operation to remove all of your breast tissue. Most mastectomy procedures remove all of the breast tissue — the lobules, ducts, fatty tissue and some skin, including the nipple and areola (total or simple mastectomy).
Newer surgical techniques may be an option in selected cases in order to improve the appearance of the breast. Skin-sparing mastectomy and nipple-sparing mastectomy are increasingly common operations for breast cancer.
Removing a limited number of lymph nodes (sentinel node biopsy). To determine whether cancer has spread to your lymph nodes, your surgeon will discuss with you the role of removing the lymph nodes that are the first to receive the lymph drainage from your tumor.
If no cancer is found in those lymph nodes, the chance of finding cancer in any of the remaining lymph nodes is small and no other nodes need to be removed.
- Removing several lymph nodes (axillary lymph node dissection). If cancer is found in the sentinel lymph nodes, your surgeon will discuss with you the role of removing additional lymph nodes in your armpit.
Removing both breasts. Some women with cancer in one breast may choose to have their other (healthy) breast removed (contralateral prophylactic mastectomy) if they have a very increased risk of cancer in the other breast because of a genetic predisposition or strong family history.
Most women with breast cancer in one breast will never develop cancer in the other breast. Discuss your breast cancer risk with your doctor, along with the benefits and risks of this procedure.
Complications of breast cancer surgery depend on the procedures you choose. Breast cancer surgery carries a risk of pain, bleeding, infection and arm swelling (lymphedema).
You may choose to have breast reconstruction after surgery. Discuss your options and preferences with your surgeon.
Consider a referral to a plastic surgeon before your breast cancer surgery. Your options may include reconstruction with a breast implant (silicone or water) or reconstruction using your own tissue. These operations can be performed at the time of your mastectomy or at a later date.
Radiation therapy uses high-powered beams of energy, such as X-rays and protons, to kill cancer cells. Radiation therapy is typically done using a large machine that aims the energy beams at your body (external beam radiation). But radiation can also be done by placing radioactive material inside your body (brachytherapy).
External beam radiation of the whole breast is commonly used after a lumpectomy. Breast brachytherapy may be an option after a lumpectomy if you have a low risk of cancer recurrence.
Doctors may also recommend radiation therapy to the chest wall after a mastectomy for larger breast cancers or cancers that have spread to the lymph nodes.
Breast cancer radiation can last from three days to six weeks, depending on the treatment. A doctor who uses radiation to treat cancer (radiation oncologist) determines which treatment is best for you based on your situation, your cancer type and the location of your tumor.
Side effects of radiation therapy include fatigue and a red, sunburn-like rash where the radiation is aimed. Breast tissue may also appear swollen or more firm. Rarely, more-serious problems may occur, such as damage to the heart or lungs or, very rarely, second cancers in the treated area.
Chemotherapy uses drugs to destroy fast-growing cells, such as cancer cells. If your cancer has a high risk of returning or spreading to another part of your body, your doctor may recommend chemotherapy after surgery to decrease the chance that the cancer will recur.
Chemotherapy is sometimes given before surgery in women with larger breast tumors. The goal is to shrink a tumor to a size that makes it easier to remove with surgery.
Chemotherapy is also used in women whose cancer has already spread to other parts of the body. Chemotherapy may be recommended to try to control the cancer and decrease any symptoms the cancer is causing.
Chemotherapy side effects depend on the drugs you receive. Common side effects include hair loss, nausea, vomiting, fatigue and an increased risk of developing an infection. Rare side effects can include premature menopause, infertility (if premenopausal), damage to the heart and kidneys, nerve damage, and, very rarely, blood cell cancer.
Hormone therapy — perhaps more properly termed hormone-blocking therapy — is used to treat breast cancers that are sensitive to hormones. Doctors refer to these cancers as estrogen receptor positive (ER positive) and progesterone receptor positive (PR positive) cancers.
Hormone therapy can be used before or after surgery or other treatments to decrease the chance of your cancer returning. If the cancer has already spread, hormone therapy may shrink and control it.
Treatments that can be used in hormone therapy include:
- Medications that block hormones from attaching to cancer cells (selective estrogen receptor modulators)
- Medications that stop the body from making estrogen after menopause (aromatase inhibitors)
- Surgery or medications to stop hormone production in the ovaries
Hormone therapy side effects depend on your specific treatment, but may include hot flashes, night sweats and vaginal dryness. More serious side effects include a risk of bone thinning and blood clots.
Targeted therapy drugs
Targeted drug treatments attack specific abnormalities within cancer cells. As an example, several targeted therapy drugs focus on a protein that some breast cancer cells overproduce called human epidermal growth factor receptor 2 (HER2). The protein helps breast cancer cells grow and survive. By targeting cells that make too much HER2, the drugs can damage cancer cells while sparing healthy cells.
Targeted therapy drugs that focus on other abnormalities within cancer cells are available. And targeted therapy is an active area of cancer research.
Your cancer cells may be tested to see whether you might benefit from targeted therapy drugs. Some medications are used after surgery to reduce the risk that the cancer will return. Others are used in cases of advanced breast cancer to slow the growth of the tumor.
Immunotherapy uses your immune system to fight cancer. Your body's disease-fighting immune system may not attack your cancer because the cancer cells produce proteins that blind the immune system cells. Immunotherapy works by interfering with that process.
Immunotherapy might be an option if you have triple-negative breast cancer, which means that the cancer cells don't have receptors for estrogen, progesterone or HER2.
Supportive (palliative) care
Palliative care is specialized medical care that focuses on providing relief from pain and other symptoms of a serious illness. Palliative care specialists work with you, your family and your other doctors to provide an extra layer of support that complements your ongoing care. Palliative care can be used while undergoing other aggressive treatments, such as surgery, chemotherapy or radiation therapy.
When palliative care is used along with all of the other appropriate treatments, people with cancer may feel better and live longer.
Palliative care is provided by a team of doctors, nurses and other specially trained professionals. Palliative care teams aim to improve the quality of life for people with cancer and their families. This form of care is offered alongside curative or other treatments you may be receiving.

No alternative medicine treatments have been found to cure breast cancer. But complementary and alternative medicine therapies may help you cope with side effects of treatment when combined with your doctor's care.
Alternative medicine for fatigue
Many breast cancer survivors experience fatigue during and after treatment that can continue for years. When combined with your doctor's care, complementary and alternative medicine therapies may help relieve fatigue.
Talk with your doctor about:
- Gentle exercise. If you get the OK from your doctor, start with gentle exercise a few times a week and add more if you feel up to it. Consider walking, swimming, yoga or tai chi.
- Managing stress. Take control of the stress in your daily life. Try stress-reduction techniques such as muscle relaxation, visualization, and spending time with friends and family.
- Expressing your feelings. Find an activity that allows you to write about or discuss your emotions, such as writing in a journal, participating in a support group or talking to a counselor.
Coping and support
A breast cancer diagnosis can be overwhelming. And just when you're trying to cope with the shock and the fears about your future, you're asked to make important decisions about your treatment.
Every person finds his or her own way of coping with a cancer diagnosis. Until you find what works for you, it might help to:
Learn enough about your breast cancer to make decisions about your care. If you'd like to know more about your breast cancer, ask your doctor for the details of your cancer — the type, stage and hormone receptor status. Ask for good sources of up-to-date information on your treatment options.
Knowing more about your cancer and your options may help you feel more confident when making treatment decisions. Still, some women may not want to know the details of their cancer. If this is how you feel, let your doctor know that, too.
- Talk with other breast cancer survivors. You may find it helpful and encouraging to talk to others in your same situation. Contact the American Cancer Society to find out about support groups in your area and online.
- Find someone to talk about your feelings with. Find a friend or family member who is a good listener, or talk with a clergy member or counselor. Ask your doctor for a referral to a counselor or other professional who works with cancer survivors.
Keep your friends and family close. Your friends and family can provide a crucial support network for you during your cancer treatment.
As you begin telling people about your breast cancer diagnosis, you'll likely get many offers for help. Think ahead about things you may want assistance with, whether it's having someone to talk to if you're feeling low or getting help preparing meals.
- Maintain intimacy with your partner. In Western cultures, women's breasts are associated with attractiveness, femininity and sexuality. Because of these attitudes, breast cancer may affect your self-image and erode your confidence in intimate relationships. Talk to your partner about your insecurities and your feelings.
Preparing for your appointment
Consulting with your health care team
Women with breast cancer may have appointments with their primary care doctors as well as several other doctors and health professionals, including:
- Breast health specialists
- Breast surgeons
- Doctors who specialize in diagnostic tests, such as mammograms (radiologists)
- Doctors who specialize in treating cancer (oncologists)
- Doctors who treat cancer with radiation (radiation oncologists)
- Genetic counselors
- Plastic surgeons
What you can do to prepare
- Write down any symptoms you're experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
- Write down key personal information, including any major stresses or recent life changes.
- Write down your family history of cancer. Note any family members who have had cancer, including how each member is related to you, the type of cancer, the age at diagnosis and whether each person survived.
- Make a list of all medications, vitamins or supplements that you're taking.
- Keep all of your records that relate to your cancer diagnosis and treatment. Organize your records in a binder or folder that you can take to your appointments.
- Consider taking a family member or friend along. Sometimes it can be difficult to absorb all the information provided during an appointment. Someone who accompanies you may remember something that you missed or forgot.
- Write down questions to ask your doctor.
Questions to ask your doctor
Your time with your doctor is limited, so preparing a list of questions will help make the most of your time together. List your questions from most important to least important in case time runs out. For breast cancer, some basic questions to ask your doctor include:
- What type of breast cancer do I have?
- What is the stage of my cancer?
- Can you explain my pathology report to me? Can I have a copy for my records?
- Do I need any more tests?
- What treatment options are available for me?
- What are the benefits from each treatment you recommend?
- What are the side effects of each treatment option?
- Will treatment cause menopause?
- How will each treatment affect my daily life? Can I continue working?
- Is there one treatment you recommend over the others?
- How do you know that these treatments will benefit me?
- What would you recommend to a friend or family member in my situation?
- How quickly do I need to make a decision about cancer treatment?
- What happens if I don't want cancer treatment?
- What will cancer treatment cost?
- Does my insurance plan cover the tests and treatment you're recommending?
- Should I seek a second opinion? Will my insurance cover it?
- Are there any brochures or other printed material that I can take with me? What websites or books do you recommend?
- Are there any clinical trials or newer treatments that I should consider?
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask additional questions that may occur to you during your appointment.
What to expect from your doctor
Your doctor is likely to ask you a number of questions. Being ready to answer them may allow time later to cover other points you want to address. Your doctor may ask:
- When did you first begin experiencing symptoms?
- Have your symptoms been continuous or occasional?
- How severe are your symptoms?
- What, if anything, seems to improve your symptoms?
- What, if anything, appears to worsen your symptoms?
