What Is an Excisional Biopsy of the Breast?
An excisional biopsy of the breast is a small surgical procedure done to remove a lump or abnormal tissue from the breast. In this procedure, the doctor removes the entire lump, not just a small sample. The removed tissue is then sent to a lab for testing. This helps doctors know whether the lump is cancerous or non-cancerous.
This procedure is often suggested when imaging tests like a mammogram or ultrasound show something unusual, or when earlier biopsy results are not clear. It is usually done under local or general anesthesia, so the patient does not feel pain during the surgery. Excisional biopsy is both a diagnostic and sometimes a treatment method, especially if the lump is fully removed. It is a common and trusted procedure used by doctors to get accurate results.
Purpose & Benefits of Excisional Biopsy of the Breast
● Helps confirm whether a breast lump is cancer or not
● Removes the whole lump for detailed testing
● Gives more accurate results than needle biopsy
● Helps doctors plan further treatment if needed
● Can remove the problem completely in some cases
● Reduces stress caused by unclear test results
Who May Need an Excisional Biopsy?
● Women with a breast lump found during self-exam
● Patients with unclear needle biopsy results
● People with abnormal findings on mammogram or ultrasound
● Women with pain, discharge, or changes in the breast
● Patients with a family history of breast cancer
● Those advised by a breast specialist or surgeon
Types of Breast Biopsy (Brief Overview)
1. Excisional Biopsy
The entire lump or abnormal area is removed through a small cut. This is the most complete type of biopsy.
2. Incisional Biopsy
Only a part of the lump is removed. This is less common today.
3. Needle Biopsy
A thin or thick needle is used to take a small tissue sample. It is less invasive but may not always give full results.
Excisional Biopsy Procedure: Step-by-Step
1. The patient is asked to avoid food for a few hours before surgery.
2. Local or general anesthesia is given to prevent pain.
3. The doctor makes a small cut over the lump area.
4. The entire lump and some surrounding tissues are removed.
5. The cut is closed using stitches or surgical glue.
6. The tissue is sent to a lab for examination.
7. The patient rests for a short time before going home.
The procedure usually takes about 30–60 minutes.
Recovery & Aftercare
Recovery after an excisional biopsy is usually quick. Most patients go home the same day. Mild pain, swelling, or bruising is normal and improves in a few days. Doctors may suggest pain medicine and keeping the area clean and dry.
Patients should avoid heavy work for a few days and follow wound care instructions carefully. Stitches may dissolve on their own or be removed later. Results are usually available within a few days to a week.
Risks & Possible Complications
● Mild pain or discomfort
● Bruising or swelling
● Bleeding at the surgery site
● Infection (rare)
● Small scar on the breast
● Temporary change in breast shape
Most risks are minor and can be managed easily with proper care.
Excisional Biopsy vs Other Breast Tests
E xcisional Biopsy
- Removes full lump
- More accurate
- Minor surgery
- Small scar
Needle Biopsy
- Removes small sample
- Less detailed
- No surgery
- No scar
Excisional biopsy gives clearer results but is slightly more invasive.
