Closed sac growth on the body

<span lang="en" dir="ltr"><span class="mw-page-title-main">Cyst</span></span>

A cyst is a closed sac in the body, having a distinct envelope and division compared with the nearby tissue. Hence, it is a cluster of cells that have grouped together to form a sac ; however, the distinguishing aspect of a cyst is that the cells forming the "shell" of such a sac are distinctly abnormal when compared with all surrounding cells for that given location. A cyst may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst may resolve on its own. Otherwise, it may need to be removed surgically, depending upon its type and location.
