Core needle biopsy

Core needle biopsy is a medical procedure used to extract a small sample of tissue for examination and diagnosis. This procedure is often used to diagnose various types of cancers, including breast cancer, lung cancer, and prostate cancer.

Procedure

The procedure involves the insertion of a hollow needle into the suspected abnormal tissue. The needle is often guided by imaging techniques such as ultrasound, CT scan, or MRI. Once the needle is in the correct position, a small sample of tissue is extracted and sent to a laboratory for examination under a microscope.

Uses

Core needle biopsy is used to diagnose various types of cancers. It can also be used to determine the stage of cancer, and to monitor the effectiveness of treatment.

Risks

While core needle biopsy is generally safe, there are some risks associated with the procedure. These include infection, bleeding, and an allergic reaction to the local anesthetic. There is also a small risk that the biopsy will not provide enough tissue for a definitive diagnosis, requiring a repeat procedure or a more invasive surgical biopsy.

Recovery

Recovery from a core needle biopsy is typically quick. Most patients are able to return to their normal activities within a day or two. Some discomfort, bruising, or swelling at the biopsy site is common, but these symptoms usually resolve within a few days.
