A breast biopsy is the removal of breast tissue to examine it for signs of breast cancer or other disorders. Several different types of biopsy may be done. This article discusses open breast biopsy. An open biopsy involves making a small cut in the breast and removing breast tissue.

An open biopsy may remove part (incisional biopsy) or all (excisional biopsy) of the area of interest. If the entire lump or area of interest is removed, this method may also be called a lumpectomy.

If the surgeon cannot easily feel the lump or cyst, breast ultrasound or mammography may be used before the biopsy. A needle or wire is placed in the area of interest. This will be left in to help the surgeon.

The biopsy will be done in an operating room.

• Usually, you lie on your back for the procedure. You may receive local anesthesia with medicine to make you sleepy or you may receive general anesthesia.
• A surgical cut is made in the skin. The wire and breast tissue around it are removed. Sometimes, testing is done at the time of the procedure, but a final diagnosis takes more time.
• After the tissue sample is taken, the cut is closed with sutures. A dressing and bandage are applied.

If you receive general anesthesia, your vital signs (temperature, pulse, rate of breathing, blood pressure) will be monitored for at least an hour after the procedure. Your health care provider may prescribe pain medication.

The health care provider will ask questions about your medical history and perform a manual breast exam.

You must sign an informed consent form. If you are going to have general anesthesia, you may be asked not to eat or drink anything for 8 - 12 hours before the test.

If you take medications (including aspirin or herbal medications), ask your doctor whether you need to stop taking these before the biopsy.

Tell your doctor if you may be pregnant before having an open biopsy.
