In a biopsy, a piece of tissue or bodily fluid is sampled from an area of the body for closer examination under a microscope. Biopsies are usually conducted when a doctor is led to believe that there may be an abnormality around the area in question. The removed tissue is sent to a lab for analysis.
Typically, biopsies are most helpful for detecting digestive cancers. However, a biopsy is useful for obtaining information from many other areas of concern other than just the surface of the skin. After conducting a biopsy, a problem can be easier to diagnose and an accurate treatment plan can be put into place going forward.
