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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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.
