Understanding Biopsy: A Diagnostic Tool

A biopsy is a medical procedure that involves examining a sample of tissue taken from the body. This helps doctors diagnose and understand various conditions, including cancer, infections, and inflammatory diseases.

Why is a Biopsy Recommended?

Doctors recommend biopsies when:

– A suspicious lesion, tumor, or mass is detected
– Changes in a mole or skin growth need to be investigated
– Chronic conditions like hepatitis or kidney disease require monitoring
– A transplanted organ needs to be checked for rejection

Types of Biopsy Procedures

There are several types of biopsy procedures, including:

1. Scraping cells: Cells are removed from the surface layer of tissue.
2. Punch biopsy: A special instrument is used to punch a small hole in the skin.
3. Needle biopsy: A hollow needle is inserted into the body, guided by ultrasound or CT scan.
4. Endoscopic biopsy: An endoscope is used to remove tissue from the target organ.
5. Excisional biopsy: Surgery is performed to remove a larger piece of tissue.
6. Fine needle aspiration: A needle and syringe are used to obtain a sample of cells.
7. Vacuum assisted biopsy: A suction device is used to collect more tissue and cells.
8. Core needle biopsy: A larger needle with a cutting tip is used to draw a column of tissue.

Areas of the Body Where Biopsy is Performed

Biopsies can be performed on various parts of the body, including:

– Bone
– Bone marrow
– Liver
– Kidney

– Skin

What Happens After a Biopsy?

After the sample is taken, it’s sent to a pathology lab for examination under a microscope. Various tests are performed, and the final results are communicated to the doctor.

By understanding what a biopsy is and how it’s performed, you’ll be better equipped to discuss your diagnostic options with your doctor.
