Core biopsy information
A core biopsy involves a doctor placing a needle into the breast to remove a small sample of tissue. Ultrasound, mammography or clinical guidance (where the doctor feels for the area to be sampled) may be used to place the needle in the correct location. The doctor will decide which method is used based on the patient's circumstances.
Core biopsy is one of a group of tests which may be used at assessment to help diagnose certain breast conditions. Although these tests are not 100% accurate, their combined use gives the best chance of detecting or excluding breast cancer.
You can withdraw your consent for a biopsy and request it be stopped at any time.
Preparing for the procedure
A core biopsy is a minor procedure, there is no need to fast before the test. Avoid using any talcum powder, body lotions, creams, perfumes or deodorant on or near the breast area before you have the core biopsy.
During the procedure
The procedure is done under a local anaesthetic. If it's done using mammography, it may take up to an hour. If the test is done using ultrasound or by clinical guidance, it may take up to half an hour.
Some bruising, swelling, discomfort or slight bleeding may occur. Very rarely, a serious complication may occur including puncture of the lung (pneumothorax) or damage to an artery. Should this occur, surgery may be necessary.
After the procedure
The procedure may leave a very fine scar of less than 5mm. This will likely fade in time.
If the area is uncomfortable, it's recommended you take paracetamol to ease the comfort. Don't take disprin, aspirin, aspalgin or other preparations containing aspirin as they may increase bruising. Applying cold packs to the area can also help easy discomfort and bruising.
