Lumpectomy vs. mastectomy: How to decide which breast cancer surgery is right for you

Compare two common breast cancer surgeries and learn how they differ in terms of survival and recurrence.

By Mayo Clinic Staff

If you've been diagnosed with early-stage breast cancer, your healthcare team may have told you that you have a choice about surgery. You may be able to choose between having a lumpectomy and a mastectomy as part of your treatment plan. How do you decide?

First, talk about it with your healthcare team. Your team knows the details of your tumor as well as your personal circumstances. The more that team members know about your lifestyle and preferences, the better they can help you weigh your options.

In the meantime, here are some common questions that people have, along with answers to help you think about your choices.

Not everyone has a choice when being treated for early-stage breast cancer. For some people, a mastectomy is necessary to remove all the cancer.

How are lumpectomy and mastectomy different?

Both lumpectomy and mastectomy are surgeries to remove breast cancer.

Lumpectomy removes the cancer and a small rim of healthy breast tissue while leaving the rest of the breast in place. It allows you to keep most of your breast. Lumpectomy typically is followed by radiation therapy to lower the risk of the cancer returning.

Oncoplastic techniques may be used with a lumpectomy when a large amount of tissue is removed compared with the size of the breast. These techniques combine cancer surgery with plastic surgery. After removing the cancer, the surgeon moves the remaining breast tissue around to fill the area where tissue was removed and help preserve breast shape.

Mastectomy removes all the breast tissue. Some mastectomy techniques can keep all the skin of the breast or keep the skin and the nipple. After mastectomy, breast reconstruction may be an option for you. Reconstruction re-creates the shape of the breast. You also may choose not to have reconstruction.

Reconstruction can be done at the same time as mastectomy or later. Mastectomy may or may not be followed by radiation. It depends on the size of the tumor and whether lymph nodes are involved.

Lumpectomy with radiation and mastectomy are options for ductal carcinoma in situ (DCIS) or early-stage invasive breast cancer.

Is a partial mastectomy the same as a lumpectomy?

Yes. Lumpectomy, wide local excision, segmental mastectomy and partial mastectomy are all ways to describe breast-conserving surgery. Breast-conserving surgery removes the cancer along with a small rim, called a margin, of healthy tissue around the cancer. It does not remove the whole breast.

Breast-conserving surgery followed by radiation therapy is called breast-conserving therapy.

Will my chance of survival be different with lumpectomy or mastectomy?

No. For early-stage breast cancers, lumpectomy followed by radiation therapy and mastectomy have similar survival results. Choosing lumpectomy doesn't mean risking a shorter lifespan if your healthcare team tells you that either surgery is an option. In the same way, choosing mastectomy doesn't result in a longer lifespan.

Several large well-designed studies, including some with 20 years of follow-up, showed that women undergoing mastectomy did not have any survival advantages over women who had breast-conserving therapy. Because of this, breast-conserving therapy has become a standard recommendation for most people with early-stage breast cancer.

Both mastectomy and breast-conserving therapy are equally effective for treating early-stage breast cancer. If the tumor can be removed with a lumpectomy, having a mastectomy instead does not improve cure rates.

Is breast cancer more likely to come back after lumpectomy or mastectomy?

Recurrence rates are generally the same after breast-conserving therapy or mastectomy. Recurrence means the cancer comes back. With today's radiation therapy, cancer medicines and other advances in treatment, recent studies show similar rates of cancer recurrence in the breast after the two approaches.

Radiation therapy after lumpectomy substantially lowers the risk of cancer coming back in the treated area. Breast cancer medicines taken after breast-conserving therapy also help lower the risk of recurrence. If the cancer comes back in the breast, it usually can be treated with more surgery — either repeat lumpectomy or a mastectomy.

Mastectomy does not reduce the recurrence rate to zero. There is a small chance that cancer can come back on the chest wall, in the skin, or in the area of the nipple and areola. Breast cancer medicines taken after mastectomy also help lower the risk of recurrence.

When is a lumpectomy typically preferred?

Lumpectomy typically is an option when the operating surgeon believes the cancer can be safely removed without leaving cancer cells behind and without compromising the shape of the breast. This may be when:

Your cancer is small compared with the size of your breast.
Your cancer is found in one or two small areas in the same breast.
Radiation therapy is an option for you after surgery.

What about mastectomy?

Mastectomy may be recommended if the cancer is too large to remove completely with lumpectomy. This may be the case if:

You have a large area of cancer compared with the overall size of your breast.
You have multiple separate areas where cancer is a concern.
Cancer is found at the edges of the removed tissue after lumpectomy, and additional tissue removal at the margin is not likely to remove the cancer completely.
You have inflammatory breast cancer.

Mastectomy also may be recommended if radiation therapy is not a good option for you. This may be the case if:

You're not able or willing to have radiation therapy after surgery.
You have a condition that may make radiation therapy less suitable, such as systemic scleroderma or lupus.
You're pregnant, as radiation could harm the developing baby. Sometimes, if you are further along in pregnancy, radiation can wait until after the baby is born.

Your breast cancer risk or personal preference may favor mastectomy. For example:

You have an inherited genetic variation, called a variant, that puts you at high risk of breast cancer. The variant typically raises your lifetime risk of a new breast cancer in either breast.
You prefer mastectomy after discussing the benefits and risks of both operations with your healthcare team.

There are different techniques for mastectomy:

Skin-sparing mastectomy. This procedure removes the breast tissue, nipple and areola, but it preserves most of the breast skin. Breast reconstruction usually is started during the same operation. This procedure may not be an option when the cancer is large or close to the skin.
Nipple-sparing mastectomy This procedure removes the breast tissue but preserves most of the breast skin, nipple and areola. It usually is followed immediately by breast reconstruction. It may not be an option if cancer is near the nipple, areola or skin.

Some treatment centers perform robot-assisted techniques for nipple-sparing mastectomy. This approach uses smaller incisions, resulting in less-visible scarring.

Some surgeons also are working to restore sensation in the nipple by using nerve grafts. This is done at the time of nipple-sparing mastectomy and reconstruction.

Does my type of breast cancer affect whether lumpectomy or mastectomy is better for me?

Lumpectomy with radiation and mastectomy are treatment options for most types of early-stage breast cancer, including:

Ductal carcinoma in situ (DCIS).
Invasive ductal carcinoma, the most common type of breast cancer.
Invasive lobular carcinoma.
HER2-positive breast cancer.
Triple-negative breast cancer.
Hormone receptor positive, HER2-negative breast cancer.
Triple-positive breast cancer.
Lymph node-negative and lymph node-positive breast cancer.

Mastectomy typically is recommended for inflammatory breast cancer.

When deciding on the type of breast surgery, the surgeon considers the size and location of the cancer relative to your breast size. Your healthcare team may recommend systemic therapy before surgery. Systemic therapy uses medicines that travel throughout the body. Examples include chemotherapy and other cancer medicines. This advice is based on the biological characteristics of your tumor, such as whether it is ductal or lobular or whether it has hormone receptors or high levels of HER2.

Should I consider a double mastectomy?

Some people undergoing mastectomy choose to have both breasts removed when only one breast has cancer. The removal of the other breast may be called a contralateral prophylactic mastectomy or a risk-reducing mastectomy. The removal of both breasts may be referred to as a double or bilateral mastectomy. Reasons people might consider a double mastectomy include:

A higher risk of breast cancer than average. People who have an inherited risk of breast cancer, such as a BRCA1 or BRCA2 genetic variant, or a strong family history of breast cancer may prefer to remove both breasts. A BRCA gene test can tell you if you have one of these variants. In this situation, a double mastectomy reduces the risk of developing breast cancer in the future. The higher your breast cancer risk, the greater the reduction in risk.
Cancer in both breasts. Removing both breasts may be part of your treatment plan when cancer is in both breasts.
A desire to lower the risk of breast cancer in the other breast. Removing the other breast lowers the risk of cancer in that breast. But for most people without a high inherited risk, the chance of developing cancer in the other breast is low. Removing the other breast does not help most people with an average risk of breast cancer live longer.
A desire to create a more even breast or chest appearance. A double mastectomy may create a more even chest appearance or possibly improve symmetry with or without breast reconstruction. However, a double mastectomy increases the extent and length of surgery and increases the risk of surgical complications. Symmetry also can be achieved by surgically shaping the opposite breast to match, without removing the entire breast.
A desire to reduce the need for future breast screening and sometimes, treatment. After a double mastectomy, you generally won't need routine mammograms. If you have DCIS, a double mastectomy may eliminate the need to take medicine to lower the risk of developing another breast cancer in the other breast.

If you're interested in a double mastectomy, talk with your healthcare team about the benefits and risks that apply in your situation.

What types of treatments come after each surgery?

Treatments after lumpectomy and mastectomy may include:

Additional surgery after lumpectomy. Sometimes, another operation is needed to clear the margins after lumpectomy if cancer cells are found at the edge of the removed tissue.
Radiation after lumpectomy. Most people have radiation therapy after they heal from lumpectomy. It is considered part of breast-conserving therapy. Radiation therapy helps lower the risk of cancer coming back in the breast. Radiation therapy has side effects, such as tiredness, rash and potential skin changes.
Radiation after mastectomy. Your healthcare team may recommend radiation therapy after mastectomy if the cancer is large, if cancer is found in your lymph nodes or if you have inflammatory breast cancer. If chemotherapy is part of your treatment plan after surgery, then radiation usually is given after completion of the chemotherapy.
Breast reconstruction after mastectomy. Mastectomy often can be combined with breast reconstruction to restore the shape of the breast. Reconstruction can be done at the same time as mastectomy or later. Completing reconstruction usually takes more than one procedure. If your treatment plan includes radiation after your mastectomy, or if you received radiation before, your healthcare team may offer specific recommendations about the timing and type of reconstruction you have.

Other parts of your treatment plan may include:

Lymph node surgery to see if cancer has spread to the lymph nodes and remove lymph nodes if necessary.
Cancer medicines, such as chemotherapy, estrogen blockers or targeted therapy. Your cancer's biological features help determine if you need any of these medicines.
Radiation therapy to the chest wall and possibly lymph nodes.

How does recovery differ between lumpectomy and mastectomy?

Lumpectomy is generally the smaller operation because less breast tissue is removed. Mastectomy is more extensive, and adding reconstruction makes the surgery and recovery more complex.

Typically, people go home the same day that they have surgery, whether it's a lumpectomy, mastectomy or double mastectomy with reconstruction. But sometimes an overnight stay is needed.

Recovery

After a lumpectomy, most people can return to their usual activities within about two weeks. Recovery may take longer depending on the amount of tissue removed and whether you had lymph node surgery or oncoplastic surgery at the same time. Most people have radiation therapy after lumpectomy. This can affect time off work or other activities. Radiation therapy also can make you feel tired and can affect your skin.

Recovery after mastectomy may take several weeks or longer, depending on reconstruction and complications. Typically, heavy lifting and return to work are restricted for six weeks after mastectomy with reconstruction. Often, multiple procedures are needed to complete reconstruction, along with time to heal between operations. Different reconstruction options may have different recovery times.

Complications

The two procedures have similar types of complications. But the complications tend to happen more often and may be more serious after mastectomy, especially with reconstruction. This is even more true in older adults.

Surgical complications may include:

Bleeding.
Delayed healing.
Infection.
Buildup of blood in the treated area, called hematoma.
Buildup of clear fluid in the treated area, called seroma.
Arm swelling, called lymphedema, if lymph nodes in the armpit are removed.

Most surgical complications can be treated successfully. Small collections of blood or fluid may go away on their own. Larger collections may need to be drained. Infections usually are treated with antibiotics and sometimes drainage. Significant bleeding is uncommon but may require another surgery to stop it.

Your healthcare team can help you understand what to expect with your planned treatment. Ask questions to help you prepare for daily life adjustments after surgery.

How might each choice affect my body and quality of life?

What it means to feel healthy and whole differs for each person. Some people feel that breasts are an important part of their identity. Others may feel less so. It's likely that a diagnosis of breast cancer has already changed your perspective in some ways.

It can be hard to know how the choice of lumpectomy with radiation or mastectomy will affect you. In general, lumpectomy may change the shape or appearance of your breast slightly depending on the amount of tissue removed and the size of your breast. Radiation also can change the skin and tissue of the treated breast.

If you have a mastectomy, your chest and breast area most likely will have areas of numbness because nerves are cut during surgery. Reconstruction can create a breast shape, but it probably won't look or feel exactly like the original breast.

Research suggests that neither choice is automatically better for every measure of quality of life. One study surveyed women about 10 years after treatment. The women had either breast-conserving surgery with radiation or mastectomy with reconstruction. Satisfaction with the breasts and physical well-being were similar between the groups. However, psychosocial and sexual well-being were better among those who had breast-conserving surgery with radiation.

It's worth discussing your concerns with your care team rather than assuming that one operation will make you feel safer or more satisfied afterward.

What should I think about when deciding between lumpectomy and mastectomy?

When considering whether to choose breast-conserving therapy or mastectomy, give yourself some time to think about your options. Breast cancer treatment usually does not begin right away.

Here are some questions that may help you organize your thoughts:

What has my surgeon told me about each option?
How important is breast preservation to me?
How do I feel about radiation?
How do I feel about mastectomy and possible reconstruction?
How much do I care about the final shape and appearance of my breasts? How important is symmetry to me? Am I willing to undergo additional procedures to achieve a certain outcome?
What recovery demands can I manage?
What does the time frame look like for different options?
Are there genetic or other medical factors that affect my options?
Is there anything about my cancer that makes my care team favor one surgery?
What would make me feel most comfortable with my decision over the long term?

It may help to talk about these questions with someone you trust and who listens well. Ask your healthcare team to explain things you don't understand. Once you understand what is medically possible, your own priorities can help guide the choice.
