Breast Biopsy

You will feel only a quick sting from the needle if you have a local anesthetic to numb the biopsy area. You may feel some pressure when the biopsy needle is put in. After a Reference fine-needle aspiration biopsy Opens New Window, core needle biopsy, or Reference stereotactic biopsy Opens New Window, the site may be tender for 2 to 3 days. You may also have some bruising, swelling, or slight bleeding. You can use an ice pack or take an over-the-counter pain medicine (not aspirin) to help relieve swelling and mild pain.

For 24 hours after the biopsy, do not do any heavy lifting or other activities that stretch or pull the muscles of your chest.

If you have general anesthesia for an open breast biopsy, you will not be awake during the biopsy. After you wake up, the area may be numb from a local anesthetic that was put in the biopsy site. You will also feel sleepy for several hours.

For 1 to 2 days after an open biopsy, you may feel tired. You may also have a mild sore throat if a tube was used to help you breathe during the biopsy. Using throat lozenges and gargling with warm salt water may help with the sore throat.

After an open biopsy, your breast may feel tender, firm, swollen, and bruised. You can use an ice pack or take an over-the-counter pain medicine (not aspirin) to help relieve swelling and mild pain. The tenderness should go away in about a week, and the bruising fades within 2 weeks. But the firmness and swelling may last for 6 to 8 weeks. You should wear a bra or sports bra for support for 2 to 3 days after the biopsy. Do not do any heavy lifting or other activities that stretch or pull the muscles of your chest.
