This involves taking a tiny sample of tissue through a needle. The needle is guided into place using ultrasound.
The sample is sent to a pathology laboratory where the specimen is later analysed. Results are usually available in 2 to 3 days.
The report will be sent to your referring doctor who will then convey these results to you.
The pathology company may also charge a gap for these services. Please discuss this with us if you have any questions.
You will be positioned in the best way to access the area to be biopsied. The area will be cleaned with antiseptic and local anaesthetic administered. A tiny incision will be made in the skin before the core needle is inserted with ultrasound guidance. It is often necessary to make more than one pass of the needle to obtain a sufficient sample.
Risks / Side Effects
Potential risks include infection and bleeding.
- Aseptic technique is used to minimise the risk of infection as much as possible.
- There may be some mild bruising at the site.
- The needle may puncture a blood vessel.
- Rarely, excessive bleeding can occur into the biopsy site.
- The biopsy may not obtain an adequate sample of tissue. This may require a repeat biopsy.
Before your Scan
Please inform us if you are on medication to thin your blood (eg. Warfarin, Aspirin or Clopidogrel). You may need to stop this prior to the procedure after discussion with your doctor.
It is important that you have someone to drive you home after the procedure.
It is essential that your previous mammogram and ultrasound films are available at the time of the biopsy. Please bring these with you to your examination if you have them.
- Steristrips and a waterproof dressing will cover the incision.
- The outer dressing should remain in place for at least 24 hours, the steristrips are left to gradually lift off after a few days.
- You will be given an ice pack to use to reduce bleeding and discomfort.
- You may eat and drink immediately after the procedure.
- You should avoid strenuous activity for 24 hours following the biopsy.
- You may experience some discomfort following the procedure
- If required, a simple analgesic such as paracetamol (Panadol), NOT Aspirin, should be sufficient.
- A small ice pack applied to the area may help settle pain.
- Bleeding and infection are potential complications. If you notice any increasing redness, swelling, fever or pain notify your referring doctor or call the clinic where the injection was performed immediately.
If you have not been contacted about your results in 1 to 2 weeks please contact your referrer.
