A biopsy is a sample of tissue collected from an organ or other
part of the body. A biopsy can be done by cutting or scraping a small piece of
the tissue or by using a needle and syringe to remove a sample, which is then
examined for abnormalities, such as cancer, by a doctor trained to look at
tissue samples (pathologist).
