"A cyst is a closed sac, having a distinct membrane and division on the nearby tissue. It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst could go away on its own or may have to be removed through surgery."
i have a lot of cysts, but i prefer to call them by their names, or just call them by a group name, such as. my friends.
