What is a Breast Biopsy?
The procedure you have had today is known as breast biopsy and has either been performed under ultrasound or mammographic control. Under local anaesthetic, a small cut has been made in the skin and small samples or cores of tissue have been removed. These will be sent to the laboratory for the Pathologist to examine under a microscope. The aim of this is to obtain a firm diagnosis.
How long should I keep the dressing on?
The small cut has been covered by a dressing; this wound will normally have sealed by the time you leave the Radiology Department. However, the dressing continues to apply pressure and helps to reduce any bruising. If possible, leave the dressing on undisturbed for 2 days.
It is very important that it should be kept clean and dry. Please avoid any vigorous exercise or heavy lifting to allow the small cut to heal. Driving and using a computer are fine. After the 2 days, it may be easier to remove the dressing whilst having a shower.
Are there any side-effects?
Pain
As the local anaesthetic wears off your breast may feel sore and uncomfortable and, if needed, you can take painkillers such as Paracetamol. Always take the tablets according to the instructions on the packet. Do not take Aspirin or Ibuprofen.
A cold compress may also be applied to the breast to ease any pain. We recommend that you continue to wear your bra during the day and a soft/sports bra may help at night.
Bruising
If the area should bleed again, apply pressure yourself. This should be enough; however, should you have any serious concerns contact your GP, who will advise you. The amount of bruising following this procedure is very variable.
It is likely that a bruise will develop around the area of biopsy; however, it may extend more widely. The bruising may take a few weeks to resolve completely.
Infection
Although great care has been taken to prevent infection, there is always a chance the wound may become infected. If pus (a thick green/yellow fluid) leaks from the wound, or your breast looks red or feels hot and swollen, then you should contact your GP.
A small amount of watery fluid may ooze from the wound, especially over the first two days, this is entirely normal, and does not indicate infection.
When will I know the result?
The biopsy samples require careful preparation before they are ready to be looked at under the microscope. The process can take up to 2 weeks before a result is available. The multidisciplinary team will meet to discuss your results and decide what to do next.
Occasionally, the results are not conclusive, and the biopsy may need to be repeated: your consultant would discuss this with you.
An appointment in the breast clinic will be arranged for you once the results are available. If you have not received a follow-up appointment within 3 weeks, please phone the surgical secretaries on 0300 613 2358 or 0300 613 4160
