A breast biopsy is the removal of breast tissue to examine it for signs of breast cancer or other disorders.
You are asked to undress from the waist up. You wear a robe that opens in the front. During the biopsy, you are awake.
You lie on your back.
The biopsy is done in the following way:
The biopsy is done using one of the following:
Once the tissue sample has been taken, the catheter or needle is removed. Ice and pressure are applied to the site to stop any bleeding. A bandage is applied to absorb any fluid. You do not need any stitches after the needle is taken out. If needed, strips of tape may be placed to close the wound.
The provider will ask about your medical history and perform a manual breast exam.
If you take medicines (including aspirin, supplements, or herbs), ask your doctor whether you need to stop taking these before the biopsy.
Tell your doctor if you may be pregnant.
DO NOT use lotion, perfume, powder, or deodorant underneath your arms or on your breasts.
When the numbing medicine is injected, it may sting a bit.
During the procedure, you may feel slight discomfort or light pressure.
After the test, the breast may be sore and tender to the touch for several days. You can do whatever activity you want as long as it does not cause pain or discomfort. Use acetaminophen (Tylenol) or ibuprofen (Advil) to relieve pain.
You may have some bruising, and there will be a very small scar where the needle was inserted.
A normal result means there is no sign of cancer or other breast problems.
Your health care provider will let you know if and when you need a follow-up mammogram or other tests.
