Lumpectomy (also called breast conserving surgery, partial mastectomy or wide excision) is often done under general anesthesia, which means you are unconscious (asleep) during the surgery. In some cases, regional anesthesia may be used.
The surgeon makes an incision (cut) in the breast and removes the tumor, along with a small rim of normal tissue around the tumor. He/she then closes the incision with stitches, trying to keep the breast looking as much like it did before surgery. The surgeon may also make an incision in the underarm area and remove some lymph nodes.
In some cases, more than one surgery is needed to get clean margins. Clean (also called uninvolved or negative) margins mean there is only normal tissue (and no cancer cells) at the edges of the tissue removed from the breast. Learn more about assessing margins.
The tissue removed during surgery is sent to a pathologist for detailed testing. Learn about the results of the tests and other information found in your pathology report.
In some cases, the surgeon uses special methods to help find the exact area of the breast that contains the tumor.
Sometimes breast cancers found by mammography (or other imaging) are nonpalpable (cannot be felt). If the tumor is nonpalpable, a procedure called wire-localization or needle-localization will be done just before surgery.
A radiologist uses a mammogram, breast ultrasound or breast MRI as a guide and inserts a very thin wire into the breast in the area of the cancer. Local anesthesia is used with this procedure.
The surgeon then uses this wire as a guide to find and remove the tumor during surgery. The wire will also be removed during surgery.
A core needle biopsy is often used to diagnose breast cancer. It removes a small amount of tumor tissue. During a core needle biopsy, a radio-opaque clip is often placed in the breast to mark the location of the tumor. (You cannot feel the clip.)
Later, when you have breast surgery, the surgeon uses the clip as guide to find and remove the tumor. The clip will also be removed during surgery.
A pathologist checks the tissue removed during surgery. By looking at the tissue under the microscope, the pathologist determines whether the entire tumor was removed. The pathologist looks at the rim of tissue (called a margin) around the tumor to check whether it contains cancer cells.

During lumpectomy for invasive breast cancer, some of the lymph nodes in the underarm area (axillary nodes) are removed to check for cancer cells. The axillary nodes are often the first place breast cancer spreads. The presence or absence of cancer in these nodes is one of the most important factors affecting cancer stage and prognosis.
Learn more about assessing axillary lymph nodes.
The length of the hospital stay after lumpectomy depends largely on whether axillary lymph nodes are removed. If you have a sentinel node biopsy or you do not have axillary nodes removed, you will likely go home the day of your surgery.
If you have axillary dissection, you may go home the same day or you may stay overnight in the hospital. A tube (surgical drain) may be placed in the underarm area to collect fluid. This drain stays in for a week after surgery.
You should discuss the expected length of your stay with your surgeon and insurance provider.

After lumpectomy, you will likely have temporary soreness in your chest, underarm and shoulder. You will also likely have numbness along the surgical incision (scar).
If axillary lymph nodes are removed during surgery, you may also have some numbness in your arm and 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.

Women may choose lumpectomy over mastectomy to keep their breast and have it look (as much as possible) like it did before surgery. However, lumpectomy will change the look of the breast. Because some tissue is removed, the breast may be smaller and firmer. There will be a scar and some numbness.
Radiation therapy (usually given after lumpectomy) can also affect the look of the breast. It can further shrink the breast and change its texture or feel.
Sometimes, factors like the location and size of the tumor can make it unlikely that a woman will be happy with the look of her breast after lumpectomy. In these cases, mastectomy (with or without reconstruction) may be the better option.
In rare cases, a woman may consider having reconstructive surgery (either at the time of their lumpectomy or later) to maintain a more natural appearance of the breast, or to match the size and shape of the opposite breast. These surgeries are complex. You may wish to meet with a plastic surgeon to discuss your options.

You may not live near the hospital where you will have your surgery. Sometimes, there are programs that offer help with local or long-distance transportation and lodging. Some also offer transportation and lodging for a friend or family member going with you. There are also financial assistance programs to help you with child care and elder care.
