Cysts

A cyst is a closed sac- or bladder-like structure that is not a normal part of the tissue where it is found. Cysts are common and can occur anywhere in the body in persons of any age. Cysts usually contain a gaseous, liquid, or semisolid substance. Cysts vary in size; they may be detectable only under a microscope or they can grow so large that they displace normal organs and tissues.
