biopsy transitive verb

Did you know?

Matter examined in a biopsy is always taken from a living organism. Most biopsies are done by using a needle to extract tissue or fluid, but some may instead require cutting, and others may amount to nothing more than swabbing the inside of the patient's cheek. Biopsies are best known as a means of detecting cancer, but a doctor may also take a biopsy of heart muscle to investigate suspected heart disease, for example, or perform a biopsy on a pregnant woman to test for disorders in the fetus.
