A doctor will need to carry out this procedure if earlier tests indicate that a particular area of the body is not well. In many cases, a biopsy is usually done after a physical examination to help in determining the best treatment option, as explained by WebMD.

There are many different types of biopsies and most of them entail removing a small body tissue for a closer examination, as noted by WebMD.
