Breast surgical biopsy is surgery to remove all or part of a breast mass. A lab will check the sample to see if there is something unusual about it.
Reasons for Procedure
Breast surgical biopsy is done to look at a suspicious part of the breast. It can find out of the spot is cancerous or not.
It may be done if there is:
- A lump
- Tissue thickening
- A nipple change
- Leaking from the nipple
- An abnormal ultrasound or mammogram
Problems are rare, but all procedures have some risk. The doctor will go over problems that could happen, such as::

What to Expect
Prior to Procedure
The doctor may meet with you to talk about:
- Anesthesia options
- Any allergies you may have

- Fasting before surgery, such as avoiding food or drink after midnight the night before
- Whether you need a ride to and from surgery
The doctor may give:

- General anesthesia —you will be asleep.
Description of the Procedure
There are a few ways the doctor can remove the mass:
Open Breast Biopsy
A small incision will be made over the area. Part or all of the mass will be removed. The site will be closed with stitches or staples. It will be bandaged.
If all of the mass is removed, then it is called a lumpectomy.

This method is used if the mass cannot be felt. Imaging is used to guide a fine wire to the breast through a needle. The wire will point to the spot that needs to be removed. A small cut will be made and the mass will be removed.
How Long Will It Take?
1 to 3 hours
Will It Hurt?
There will be some discomfort after the procedure. Medicine will help.
