Biopsy

A biopsy is a procedure used to remove a small piece of tissue from the body in order to examine it for signs of disease. It is an important tool used to diagnose many kinds of diseases, such as cancer and infections. Through a biopsy, doctors can gain insight into the extent of a patient's illness and make an appropriate treatment plan. Biopsy specimens are typically examined through a microscope and tests like immunohistochemistry, flow cytometry, and DNA analysis, allowing physicians to more accurately diagnose illnesses and monitor a patient's response to treatment.
