What Is It?
A biopsy is a procedure that removes a small amount of tissue for examination in a laboratory. Biopsies are done to diagnose many diseases, especially cancer. In some cases, biopsies help to determine prognosis and appropriate treatment. There are different biopsy techniques, depending on which tissue or organ is being sampled.
Biopsies can take as little as a minute for a simple skin biopsy or up to an hour or more for deep biopsies.
