Core Needle Biopsy in Koramangala, Bangalore

A core biopsy is an invasive procedure carried out by a doctor and a local anesthetist to examine tissues under a microscope to probe for abnormalities. The biopsy can be performed on nearly all areas of the body, but it is most likely performed on abnormal areas related to the prostate, breast, or lymph nodes.

What Is Core Biopsy?

A core biopsy is a surgical procedure in which a needle is inserted through the skin to help remove mass or lump tissues from the body. It is found to be highly effective than a surgical biopsy as it is less invasive and quick.

When Should You Consult a Doctor?

You must seek immediate medical help in cases where a suspicious lump is protruding or found, for instance, a breast lump or an enlarged lymph node. Medical intervention is also suggested when abnormalities are detected in imaging tests, including X-rays, ultrasound, or mammography.
Here are a few signs that indicate the need for a core biopsy:

  • The growth of a lump or mass.
  • Various infections.
  • Inflammation of the affected areas.
  • The occurrence of an abnormal area in an imaging test, like x-ray or ultrasound.
  • To validate the growth and type of tumors.
  • To check the development and grade of cancer.

How to Prepare for a Core Biopsy?

Medical history: First, the doctor can ask you certain questions about your medical history to ensure you are well-prepared to go under the knife.

Imaging procedures: You will need to undergo tests like a CT scan or ultrasound to allow the doctor to view the target area and proceed to the next step. These imaging procedures can also be performed during the biopsy, depending on the complexity of the surgery for which your body is being biopsied.

Local anesthesia: The core biopsy procedure is initiated after administering a local anesthetic to numb the area where the needle will be inserted. A small incision or cut is made into the skin over the lump, following which a needle is inserted through the incision. When the needle tip approaches the area that needs to be examined, a specially-designed hollow needle is used to collect the required sample of cells. Once the needle is withdrawn, the sample is extracted. Generally, this is repeated up to five times to ensure an adequate amount is retrieved.

Exceptions: Under certain instances, the mass or lump from which the cells are to be extracted are not easily felt through the skin. In this case, the radiologist, surgeon, or pathologist in charge of collecting the sample may use ultrasound to see the needle on the ultrasound monitor and get accurate guidance to reach the correct area. To explain this with an example, let us consider stereotactic mammography. It is carried out for breasts and uses two mammograms placed at different angles with a computer to locate the correct area. However, these processes may make the procedure longer. Once all the tests are completed, the biopsy site will be covered with a small dressing that will be removed the next day.

Benefits of Core Biopsy Surgeries

Core biopsies are useful in investigating the abnormalities detected on imaging tests, such as X-rays, and detect the type of breast microcalcification.

Potential Risks of the Core Biopsy Surgeries

Although there are no general complications attached to the biopsy, one may experience some bruising or tenderness at the needle insertion site. In cases of bleeding, swelling, fever, and prolonged pain, it is recommended you contact your doctor immediately.


Overall, a core biopsy can be described as a quick and effective tool that evaluates and diagnoses suspected lumps or masses. It offers a rapid diagnosis of cancer and curtails the need for surgery. It is highly recommended in medical instances where doctors need to determine if a lump is non-cancerous.
