When a scan or examination finds a lump or suspicious area, your doctor often needs a piece of actual tissue — not just a few cells — to make a confident diagnosis. That is exactly what a core needle biopsy in Delhi provides. Using a fine hollow needle guided by ultrasound or CT, small cylinders of tissue are removed from the target through a tiny skin puncture, giving the pathologist enough to diagnose the condition precisely. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, core needle biopsy (also called tru-cut biopsy) is performed accurately under image guidance.
This guide explains what a core needle biopsy is, how it differs from FNAC, which lumps it is used for, and what to expect.

What Is a Core Needle Biopsy?
A core needle biopsy (CNB), often called a tru-cut biopsy, is a minimally invasive procedure that removes one or more small cores (cylinders) of tissue from a lump, organ or abnormal area. Because it takes actual tissue — not just loose cells — the pathologist can study the tissue architecture (histopathology) and run additional tests on it. It is done through a needle-sized puncture under local anaesthesia, with no surgical cut and no stitches, and is guided in real time by ultrasound or CT to reach the target safely.
Core Needle Biopsy vs FNAC — What Is the Difference?
Both are needle tests, but they give different information. An FNAC uses a very thin needle to draw out cells (cytology) — quick and ideal as a first check. A core needle biopsy uses a slightly thicker needle to remove tissue (histology), which allows a more complete and definitive diagnosis, including cancer type and grade and special stains such as immunohistochemistry. When a firm tissue diagnosis is needed — for example to plan cancer treatment — a core biopsy is usually preferred. For a fuller comparison, see our guide on FNAC vs core needle biopsy.
Which Lumps and Organs Can Be Sampled?
Core needle biopsy is versatile and can be performed almost anywhere a needle can safely reach under imaging, including:
- Breast lumps — a core biopsy gives receptor tests (ER, PR, HER2) needed for treatment
- Lymph nodes — for lymphoma, tuberculosis or metastatic cancer
- Liver, kidney and other organ lesions seen on imaging
- Prostate — via a transrectal approach
- Lung and deep masses — usually under CT guidance
- Soft-tissue and bone lesions in selected cases

Why Image Guidance Matters
Guiding the needle with ultrasound or CT lets the radiologist watch the needle reach the exact target in real time, avoiding blood vessels and other organs. This makes the biopsy more accurate — fewer inconclusive samples and repeat tests — and safer, especially for small, deep or hard-to-feel lesions. It is the reason image-guided core biopsy has become the standard for tissue diagnosis.
How the Procedure Works
A core needle biopsy is quick and well tolerated:
- Imaging: the target is located on ultrasound or CT and the safest path chosen.
- Cleaning & anaesthesia: the skin is cleaned and numbed with local anaesthetic.
- Sampling: under live imaging, the core needle takes one or more tissue cores — you may hear a soft click with each core.
- Finish: a small dressing is applied (no stitches) and you rest briefly before going home.
Is a Core Needle Biopsy Painful or Safe?
Because the area is numbed, most people feel only pressure and the click of the device during sampling. It is a very safe, minimally invasive procedure; minor bruising or soreness for a day or two is the most common after-effect. Serious complications are uncommon and are minimised by real-time image guidance and sterile technique.
Your Report and Next Steps
Because a core biopsy provides tissue, the histopathology report gives a detailed diagnosis — whether the lump is benign or malignant, and if malignant, its type and grade, plus any receptor or special tests needed to plan treatment. Reports typically take a few days as the tissue is carefully processed. Your treating doctor then uses this to decide the next step, whether that is reassurance, treatment or further tests.

Frequently Asked Questions
Is a core needle biopsy better than FNAC?
For a definitive tissue diagnosis — including cancer type, grade and receptor tests — a core needle biopsy is usually preferred, while FNAC is a quick first check using cells. Your doctor decides which you need, and sometimes both are used.
Is a core needle biopsy painful?
The area is numbed with local anaesthesia, so most people feel only pressure and the click of the needle device. Mild soreness afterwards settles in a day or two.
How many tissue samples are taken?
Usually a few small cores are taken to ensure the sample is adequate for accurate diagnosis and any additional tests.
When will I get the report?
Core biopsy (histopathology) reports usually take a few days, as the tissue is processed carefully and special tests may be added.
Is there any downtime after the biopsy?
Very little. It is a day-care procedure and most people resume normal activity the same day, avoiding heavy lifting briefly as advised.
