A medical procedure in which a sample of cells or tissue is removed from the body for examination.
A biopsy allows healthcare professionals, especially pathologists, to examine tissue or cells for abnormalities. Depending on the situation, the sample may be examined under a microscope, tested for specific molecules, or subjected to other laboratory analyses.
Biopsies are commonly used to investigate suspected cancers, unexplained inflammation, infections, and other abnormalities. The procedure can range from removing a small sample with a needle to surgically removing a larger piece of tissue.
QUICK FACT
A biopsy does not automatically mean cancer is suspected. It can be used to investigate many different conditions.
