Your breast is first scanned by an ultrasound Technologist to locate the target lesion. The Radiologist will discuss the procedure with you and answer any questions you may have.

At the start of the procedure, your skin is sterilized and sterile drapes are placed at the biopsy site. A local anesthetic is infused into the breast in order to diminish discomfort during the biopsy. The Radiologist uses ultrasound to guide the biopsy needle into an appropriate position to sample the lesion in question. When the sample is taken, there may be a pinching sensation. If pain is experienced, the Radiologist can administer additional local anesthetic to keep you comfortable.

A few samples are required to provide enough tissue for the Pathologist to give a definitive diagnosis. At the end of the procedure, a bandage will be placed on the skin.

What occurs after the test?

After the procedure there may be a slight amount of discomfort which can be addressed with a cold compress and some acetaminophen.

You may have a small bruise at the site of the needle puncture. It is important to keep the puncture site dry until a scab forms to prevent infection.

Biopsy results return in approximately two (2) weeks, at which time you should discuss the findings with their physician.
