Breast Biopsy

A breast biopsy takes a small sample of tissue or cells from an area in the breast, such as a lump, a suspicious shadow on a mammogram or a cluster of calcium specks, so a pathologist can examine it under the microscope. It is the only way to be sure whether a breast change is benign or cancer.

Most breast biopsies, around four in five, show a benign cause. When cancer is found, the sample also reveals its type, grade and receptor status, which steer every later treatment choice.

What Breast Biopsy shows

The pathologist reports whether the tissue is normal, benign (for example a fibroadenoma, cyst wall or fat necrosis), a lesion of uncertain potential such as atypical hyperplasia or a papilloma, carcinoma in situ, or invasive cancer. For cancers, the report gives the type (ductal, lobular or other), the grade, and whether the cells carry oestrogen and progesterone receptors and HER2. These markers decide whether hormone therapy, targeted therapy or chemotherapy is likely to help. The radiologist then checks that the pathology result fits the imaging appearance; if it does not, a repeat or larger sample is recommended.

When Breast Biopsy is recommended

• A new breast lump that imaging cannot confirm as a simple cyst
• A mammogram, ultrasound or MRI finding graded BI-RADS 4 or 5
• Suspicious microcalcifications seen on a mammogram
• Nipple changes such as crusting, inversion or bloody discharge with an imaging abnormality
• An enlarged armpit lymph node next to a suspicious breast finding
• A benign-looking lump that is growing

Limits and situations where another test is better:

• A simple fluid-filled cyst, which needs no biopsy and can be drained if uncomfortable
• Findings graded BI-RADS 3, where a short-interval follow-up scan is usually preferred
• Fine needle aspiration gives cells only and cannot always separate in situ from invasive cancer; core biopsy is more informative
• A benign result that does not match a worrying scan is not final and needs repeat sampling

How to prepare

• Bring all previous mammograms, ultrasound and MRI images and reports
• Tell the team about blood thinners, aspirin or clotting problems; some drugs are paused for a few days
• Mention allergies to local anaesthetic, latex or dressings
• Wear a supportive bra and a two-piece outfit
• Eat normally; fasting is only needed for surgical biopsy under general anaesthetic

What happens during the test

For an ultrasound-guided core biopsy you lie on your back, the skin is numbed with local anaesthetic, and a hollow needle is passed through a tiny nick to take 3 to 6 slivers of tissue; each sample makes a loud click. It takes 20 to 30 minutes. Calcifications are sampled with stereotactic (mammogram-guided) vacuum-assisted biopsy, with the breast held in compression for about 30 to 45 minutes. A tiny titanium marker clip is usually left at the site. Firm pressure is applied afterwards.

Results and next steps

Pathology takes about 3 to 7 working days; receptor tests may add a few days. Results should be given in person or by video call by a doctor who can explain them. A benign, concordant result means routine follow-up. Atypical or uncertain lesions often lead to vacuum or surgical excision. A cancer diagnosis leads to staging tests and a multidisciplinary plan covering surgery, drug treatment and radiotherapy.

• Test time: 20 to 45 minutes
• Results ready: 3 to 7 working days
• Back to everyday activity: Avoid heavy lifting for 24 to 48 hours

Safety and risks

• Bruising and tenderness for several days
• A haematoma, a firm swelling of collected blood
• Infection, which is uncommon
• A missed target giving a falsely reassuring result, which is why imaging and pathology are cross-checked
• Very rarely, a punctured lung lining during biopsy of deep lesions

Arranging Breast Biopsy in Türkiye

Travelling only for a breast biopsy rarely makes sense: it is quick, widely available, and the result usually leads to treatment that you will want close to home. It can be reasonable if waiting times at home are long, if you are already abroad for a check-up when a suspicious finding appears, or if you plan to have your cancer surgery in the same centre. Ask for the full pathology report in English, the slides or blocks on request, and the images on disc.
