Core Biopsy

A core biopsy involves the Radiologist guiding a specialised biopsy needle into the breast lesion to retrieve a small sample of tissue. The biopsy is performed under ultrasound guidance to ensure the needle is placed in the correct location.

There is no special preparation needed before a core biopsy. If you are taking blood thinning medications such as Warfarin, Xarelto or Aspirin, please let booking staff know.

You may need to reduce or cease this medication before the day of the procedure. Please consult with your referring Doctor.

Please let the Radiologist or Sonographer know if you are diabetic, as cortisone will increase blood sugar levels over the next few days.

You may be asked to change into a gown before your procedure and brought into an ultrasound room. The procedure will be explained to you by the Sonographer who may also take some images.

The Radiologist will clean the site of the procedure and give you a local anaesthetic to numb the area. There will be a stinging sensation from the local anaesthetic which will pass quickly.

A small incision is then made into the skin, and the biopsy needle is guided into the lesion. There should not be any pain during this, but you may feel some pressure from the needle.

A small sample of tissue is taken from the lesion. The needle will make a loud clicking sound when the sample is taken. This will be demonstrated to you before the procedure. The biopsy may be repeated to ensure adequate sample is taken.

After the procedure a small waterproof dressing will be applied to the site. Please keep this on for 48 hours.

The sample is sent to a pathology company for interpretation.

The results will be sent to your referring Doctor who should receive the results in about two to five working days. Please consult your Doctor for any follow up.

Some bruising, bleeding and discomfort may occur. If the area is uncomfortable following the procedure, a paracetamol may be taken. Please do not take Aspirin as this as this may increase the amount of bruising. A cold pack may also be used to ease any discomfort. Bruising may take a few weeks to disappear.

We advise you not to drive for 24 hours following the procedure, so please take this into consideration when booking your appointment.
