Lumpectomy (also known as breast conserving surgery, partial mastectomy or wide excision) is a surgery to remove cancer from the breast.
Unlike a mastectomy, a lumpectomy removes only the tumor and a small rim of normal tissue around it. It leaves most of the breast skin and tissue in place.
With lumpectomy, the breast looks as close as possible to how it did before surgery. Most often, the general shape of the breast and the nipple area are kept.

Radiation therapy is usually given after lumpectomy to get rid of any cancer cells that may remain. These cells are too small to see on scans or to measure with lab tests.
Radiation therapy can lower the risk of :
Survival with lumpectomy plus radiation therapy is the same as with mastectomy .
After lumpectomy, chemotherapy, hormone therapy and/or targeted therapy may be given.
Lumpectomy plus radiation therapy is an option for most women who have early breast cancer or ductal carcinoma in situ (non-invasive breast cancer).
Lumpectomy may also be an option for some women with locally advanced breast cancer after treatment with neoadjuvant therapy (drug therapy given before surgery).
In some cases, neoadjuvant therapy can shrink a tumor enough so lumpectomy plus radiation therapy becomes an option to mastectomy.

Not everyone can have radiation therapy. Being pregnant or having certain health conditions can make radiation therapy harmful.
A mastectomy may be the best surgical option when:
Although the exact treatment for breast cancer varies from person to person, guidelines help ensure high quality care. These guidelines are based on the latest research and agreement among experts.
The National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO) are respected organizations that regularly review and update their guidelines.
In addition, the National Cancer Institute (NCI) has treatment overviews.
Talk with your health care providers about which treatment guidelines they use. Since there’s often a lag time between the latest research and guideline updates, most providers prefer to base their treatment on the latest research.
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 and feel of the breast. Because some tissue is removed, the breast may be smaller and firmer. There will also 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.
The look and feel of your breast will continue to change during the first 1-2 years after surgery and radiation therapy.
Sometimes, things like the location and size of the tumor make it unlikely a woman will be happy with the look of her breast after lumpectomy. In these cases, mastectomy (with or without breast reconstruction) may be the better option.
In rare cases, a woman may have reconstructive surgery (either at the time of the lumpectomy or later) to maintain a more natural appearance of the breast, or to match the size and shape of the other breast. These surgeries are complex, so it’s best 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 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 programs to help you with child care and elder care costs.
