Core biopsies are a less invasive procedure than an excisional biopsy.
Diagnosis using core biopsy
This is the most common type of biopsy and is similar to a fine needle aspiration (FNA), but it uses a slightly wider, hollow needle to remove a small piece of breast tissue from the area of concern.
Advantages of core biopsy
Removing a piece of tissue, rather than just cells allows the pathologist to examine any areas of concern in detail and it often gives more information than fluid and cells taken by an FNA. It is less invasive than an excisional biopsy and will leave no scars.
What to expect during a core biopsy
You will be given a local anaesthetic to numb the relevant area, and once it takes effect a small nick or cut is made in the skin and the biopsy needle is carefully inserted.
Usually, a few samples are required and you may hear a clicking noise as each one is taken.
It may feel slightly uncomfortable but the local anaesthetic will stop it feeling painful.
Once the samples have been taken, the area will be pressed on firmly to help reduce any bleeding and bruising and then it will be covered with a dressing. The area may feel sore for a few days following the biopsy, but it should soon clear up. We will fast-track your biopsy results to ensure you know the outcome within a week, sometimes sooner, and will contact you with details of a follow-up appointment to discuss them.
