What is a lumpectomy?

A lumpectomy is removal of only a breast mass, and not the whole breast. The mass is removed, along with a small area of surrounding normal breast tissue. The borders of the tissue removed are called surgical margins. If cancer is found, these “margins” should not contain any cancer. This reduces the risk of cancer growing back in that breast.

Will I stay overnight?

No. This is usually done as an outpatient or "same day" surgery.

Could I need more surgery?

If the pathology report says that cancer is seen at or close to the surgical margin, more surgery may be needed to obtain "clear margins."

What is recovery like?

Your surgeon will talk to you about specific recovery issues. In general, you will be up and moving the day after surgery. You will have some limitations to your normal schedule and exercise routine in the first week or so. After surgery, you could have any of the following issues, which will resolve over time:

  • Pain or sensitivity in surgery area.
  • Breast swelling.
  • Bruising.
  • Lump or firmness at the surgical site.

Can I prevent infections?

Getting an infection after lumpectomy is not common. You can help prevent an infection by:

  • Take a shower the night before surgery and wash your body with soap and water.
  • Do not immerse the incision site in water (soaking in a tub or swimming).
  • Always wash your hands before and after touching the incision or changing the dressing. 

What will I need at home?

  • A supportive, cotton bra or sports bra to wear the days and weeks after surgery. 
  • Gauze pads (4x4) to place inside your bra for comfort and protection (no need to use any tape). Gauze pads can be found at your supermarket or pharmacy.
  • Clean, supportive pillow(s) to put under your arm while sitting or to help with positioning at night.
  • You may have constipation after surgery. Over-the-counter medications, adding fiber to your diet, exercise (as simple as walking) and fluids may ease constipation. Ask your health-care team about over-the-counter medications that may work for you.

General Incision Care

If you have a post-surgical bandage, remove per your surgeon's instructions (often within 48 hours). Once the bandage is removed, you may shower, but do not scrub the incision. To dry, carefully pat the incision with a clean towel. Avoid lotions, powders or deodorant on or near the incision during the first 1-2 weeks until it is fully closed.

Most surgeons use dissolvable sutures inside your body which will go away on their own. On the outside, your surgeon may use surgical glue, paper tape called "steri-strips" or nothing at all. Both glue and steri-strips can get wet in the shower.

How can I care for myself?

You may need a family member or friend to help you with your daily tasks until you are feeling better. It may take some time before your team tells you that it is ok to go back to your normal activity.

Be sure to take your prescribed medications as directed to prevent pain, infection and/or constipation. Call your team with any new or worsening symptoms.

There are ways to manage constipation after your surgery. You can change your diet, drink more fluids, and take over-the-counter medications. Talk with your care team before taking any medications for constipation. 

Taking deep breaths and resting can help manage pain, keep your lungs healthy after anesthesia, and promote good drainage of lymphatic fluid. Try to do deep breathing and relaxation exercises a few times a day in the first week, or when you notice you are extra tense.

  • Example of a relaxation exercise: While sitting, close your eyes and take 5-10 slow deep breaths. Relax your muscles. Slowly roll your head and shoulders.
