Who is it for?
Breast biopsy clarifies a suspicious finding on mammography or ultrasound (categories where biopsy is recommended in the international BI-RADS assessment). The aim is to avoid unnecessary surgery and to start any needed treatment at the right time.
A biopsy recommendation does not mean cancer: a substantial share of biopsied breast findings turn out benign. Only tissue examination gives the definitive answer.
How it is done — step by step
Planning
The lesion is re-imaged with ultrasound and the safest needle path chosen.
Local anaesthesia
The skin and the area around the lesion are numbed.
Sampling
Several cores are taken with a tru-cut needle under ultrasound guidance; each pass lasts seconds. Fine-needle aspiration may be preferred in selected cases.
Marking and finish
When appropriate, a rice-grain-sized marker (clip) may be left in the lesion — it clarifies the target later and causes no harm. Pressure and a small dressing finish the procedure.
What to expect on the day
No fasting is needed; tell us in advance if you use blood thinners. The visit usually takes 15–30 minutes.
After brief compression you go home the same day. A supportive bra adds comfort in the first days.
Risks and Limitations
The most common effects are bruising and tenderness, settling within days. Significant bleeding (hematoma) and infection are rare.
A limit: rarely, the sample may not represent the whole lesion; if pathology and imaging disagree, repeat biopsy or surgical sampling is considered. This concordance check is a standard part of the process.
Recovery and follow-up
You can return to daily life the same day; avoid heavy arm exercise for 24 hours.
Pathology is usually ready within days to a week. The result is reviewed — with the breast surgery and oncology teams when needed — and the roadmap drawn together.

Frequently Asked Questions
A biopsy was recommended — does that mean I have cancer?
No. Biopsy is the standard way to clarify a suspicious finding, and a substantial share of biopsied findings prove benign.
Is it painful?
It is performed under local anaesthesia; most patients feel only pressure. Tenderness afterwards responds to simple painkillers.
Is the clip harmful?
No — the rice-grain-sized titanium marker causes no problems, does not set off alarms and does not interfere with imaging, including MRI.
Can biopsy spread the cancer?
There is no reliable evidence that breast biopsy spreads cancer; it is the worldwide standard of diagnosis, and no treatment plan can be built without tissue diagnosis.
When is the result ready?
Usually within days to a week. We review it together and involve the relevant teams if needed.
Can it be done while breastfeeding?
Yes when needed; planning accounts for rare issues such as milk fistula, together with your physician.
