lumpectomy (also called breast conserving surgery).
First, talk with your surgeon to see if you have a choice between mastectomy and lumpectomy plus radiation therapy.
If both are options, weigh the risks and benefits of each surgery and choose the one that’s right for you.
Remember, survival is the same no matter which option you choose .
In select cases, neoadjuvant (preoperative) therapy can change a woman’s surgical options.
Neoadjuvant therapy may shrink a tumor enough that a lumpectomy becomes an option to a mastectomy.
Learn more about neoadjuvant therapy.
Lumpectomy plus radiation therapy and mastectomy have the same :
Compared to mastectomy, there is a slightly higher rate of the cancer returning to the breast (called local recurrence) with lumpectomy . A recurrence must be treated.
The risk of cancer spreading to other organs (called metastasis or distance recurrence) is the same for both procedures .

Some things to consider when choosing between mastectomy and lumpectomy plus radiation therapy are outlined in Figure 5.3 below.
The main benefit of lumpectomy plus radiation therapy is the breast is preserved as much as possible.
A potential benefit of mastectomy is radiation therapy may be avoided.
Although some women will need radiation therapy after mastectomy, many will not. (Ask your health care team if you are likely to avoid radiation therapy if you have a mastectomy.)
Radiation therapy has some side effects and requires daily trips to a treatment center.
If you live in an area without access to a radiation treatment center, or if you cannot have radiation therapy, mastectomy is usually a better option than lumpectomy.
Figure 5.3: Total mastectomy versus lumpectomy plus radiation therapy
Lumpectomy plus radiation therapy
Treatment for early breast cancer
Amount of tissue removed
Part of the breast (tries to keep the original look of the breast)
Extent of surgery
Major surgery with general anesthesia
Less extensive surgery with general or regional anesthesia
At least one overnight hospital stay needed
Often go home on same day as surgery (if axillary dissection is not done)
Almost always done
Temporary soreness of chest, underarm and shoulder
Chance of recurrence in the breast (local recurrence)
Very low for early stages of breast cancer
Low for early stages of breast cancer (but slightly higher than with mastectomy)
Chance of recurrence outside the breast (metastasis, distant recurrence)
Same as with lumpectomy plus radiation therapy
Same as with mastectomy
Chance of lymphedema (if have a sentinel node biopsy or axillary dissection)
With either type of surgery, you are likely to have some soreness in your chest, underarm and shoulder.
After mastectomy (with or without breast reconstruction), you will be numb across your chest (from your collarbone to the top of your rib cage).
Unfortunately, this numbness is usually permanent. You may get some feeling back over time, but it will never be the same as before surgery.
After lumpectomy, you are likely to have numbness along the surgical scar.
If lymph nodes in the underarm area (axillary nodes) are removed during surgery, you may also have some numbness under or behind your arm.
Learn more about the management of surgery-related pain.
If axillary nodes are removed during surgery, there is some risk of lymphedema.
Lymphedema is a condition where fluid collects in the arm (or other area such as the hand, fingers, chest or back), causing it to swell.

The type of surgery you have does not affect whether you will have chemotherapy, hormone therapy or targeted therapy.
These drug therapies are given based on the characteristics of the tumor, not the type of surgery you have.
Learn about tumor characteristics and other factors that affect these treatment options.
Lumpectomy rates vary across the U.S.
Lumpectomy is more common among women who live on the East and West Coasts, with the highest rates in the Northeast [8-9].
For example, from 2000-2006 (most recent data available), about 72 percent of women in Connecticut with early breast cancer had a lumpectomy versus about 54 percent of women in Iowa .
Part of the differences in rates is due to preferences that can vary based on where a woman lives.
For example, women who live far from a center that offers radiation therapy (needed for lumpectomy) may prefer to have a mastectomy.
Other factors also play a role.
Personal preference matters a lot. Some women very much wish to keep their breasts, while for other women mastectomy offers peace of mind.
Among women with equal access to health care, there doesn’t appear to be a difference in rates of lumpectomy between African-American and white women .
For a table showing differences in U.S. rates of mastectomy, visit the Breast Cancer Research Studies section.
Lumpectomy plus radiation therapy is not an option for all women. Talk with your health care provider about whether it’s an option for you.
Learn about the risks and benefits of your surgery options. Talk with your provider about which treatments are best for you. This can help you feel confident that you are getting the best care possible.
Never hesitate to get a second opinion from providers at different hospitals or practices. This is especially important if you aren’t satisfied with the rationale for your treatment plan.
